Abstract

Methods and systems are presented for prefetching music for devices. The disclosed method includes detecting an access to a music library through a device. The music library is associated with a user music account and is managed in cloud music storage. The disclose method further includes monitoring use activities for the user music account and the use activities of selected songs in the music library are adjustable for relevance based on assigned weightings. One or more songs from the music library that satisfy a prefetching constraint based on the monitored use activities are identified. The songs that satisfy the prefetching constraint are tagged for transferring to the device. The tagged songs are transferred to the device without receiving a user initiated request for the tagged songs.

Claims

1. A method comprising:

defining activity values for each of a plurality of use activities associated with digital music files that are stored in a server and associated with a user record, where the activity values are determined based on pre-defined rules;

receiving a transmission of use data regarding recorded use activities of the digital music files associated with the user record;

determining weighting values for each of the plurality of use activities based on the received use data;

determining a pre-fetching constraint value;

identifying digital music files that satisfy the pre-fetching constraint value based on the associated activity values and weighting values; and

transferring the identified digital music files to a first device associated with the user record without receiving a user request for the identified digital music files.

2. The method of claim 1, wherein the pre-fetching constraint value is calculated to capture music files that the user is likely to play.

3. The method of claim 1, wherein the use data includes social interactions obtained from a social network that the user participates in.

4. The method of claim 3, wherein the social interactions include one or more interactions selected from the group consisting of:

the user sharing the music file with social network friends, the user liking/disliking the music file on the social network, and the user'"'"'s social network friends liking/disliking the music file on the social network.

5. The method of claim 1, wherein the plurality of use activities include one or more activities selected from the group consisting of:

a number of times that the digital music file has been played, a number of times that the digital music file has appeared in any playlist created by the user, a last time that the digital music file was played, and a user rating of the digital music file.

6. The method of claim 1, wherein the activity values vary depending upon the type of use activity to which the respective activity value is associated.

7. The method of claim 1, wherein identifying the digital music files that satisfy the pre-fetching constraint comprises:

calculating pre-fetching scores for digital music files associated with the user record, the pre-fetching scores being based on the respective activity values and weighting values of each digital music file; and

analyzing the pre-fetching scores at pre-determined intervals to search for digital music files that have pre-fetching scores that satisfy the pre-fetching constraint.

8. The method of claim 1, wherein transferring the identified digital music files comprise:

identifying whether the first device is a mobile device; and

transferring the identified digital music files when the first device is identified as being a mobile device.

9. The method of claim 8, wherein the first device is identified as being a mobile device based on a transmission from a device identifier in the first device.

10. A system, comprising:

a cloud storage server to store user records and digital music files that are associated with the user records;

a user access module configured to receive a transmission of use data regarding use activities of the digital music files associated with the user records;

a prefetching logic module configured to

define activity values for each of a plurality of use activities associated with the digital music files, where the activity values are determined based on pre-defined rules,

determine weighting values for each of the plurality of use activities based on the received use data,

determine a pre-fetching constraint value,

identify digital music files that satisfy the pre-fetching constraint value based on the associated activity values and weighting values, and

transfer the identified digital music files to a first device associated with the user record without receiving a user request for the identified digital music files; and

at least one processor configured to execute the user access module and the prefetching logic module.

11. The system of claim 10, wherein the pre-fetching constraint value is calculated to capture music files that the user is likely to play.

12. The system of claim 10, wherein the use data includes social interactions obtained from a social network that the user participates in.

13. The system of claim 12, wherein the social interactions include one or more interactions selected from the group consisting of:

the user sharing the music file with social network friends, the user liking/disliking the music file on the social network, and the user'"'"'s social network friends liking/disliking the music file on the social network.

14. The system of claim 10, wherein the plurality of use activities include one or more activities selected from the group consisting of:

a number of times that the digital music file has been played, a number of times that the digital music file has appeared in any playlist created by the user, a last time that the digital music file was played, and a user rating of the digital music file.

15. The system of claim 10, wherein the activity values vary depending upon the type of use activity to which the respective activity value is associated.

16. The system of claim 10, wherein the prefetching log is further configured to identify the digital music files that satisfy the pre-fetching constraint by:

calculating pre-fetching scores for digital music files associated with the user record, the pre-fetching scores being based on the respective activity values and weighting values of each digital music file; and

analyzing the pre-fetching scores at pre-determined intervals to search for digital music files that have pre-fetching scores that satisfy the pre-fetching constraint.
