Abstract

Automatic and assisted playlist generation is accomplished by collecting data from users of a world-wide music information system. Attributes of the recordings listened to by users are extracted from data collected when the users access the music information system. The attributes are correlated with other attributes in the system to verify data accuracy. Users can specify a set of attributes of their music collection for automatic generation of a playlist. The playlist can then be further edited, even on devices with a limited display and a few buttons designed for playback of recordings, by re-mapping the functions of the buttons for playlist generation.

Claims

1. A method for creating playlists, comprising;

aggregating data collected from users related to recordings possessed by the users;

creating attributes for the recordings; and

generating playlists based on the attributes and user input.

2. A method as recited in claim 1, wherein the attributes include intrinsic objective attributes, intrinsic subjective attributes, extrinsic objective attributes and extrinsic subjective attributes.

3. A method as recited in claim 2, wherein the intrinsic objective attributes include at least one audio fingerprint.

4. A method as recited in claim 2, further comprising combining at least one of the intrinsic objective attributes with at least one of the extrinsic objective attributes to correct the data collected from the users.

5. A method as recited in claim 2,

further comprising transmitting from a server to a client device, at least a portion of the attributes for at least one recording accessible by the client device, and

wherein said generating includes selecting at least one of the attributes transmitted from the server in response to the user input.

6. A method as recited in claim 1, further comprising obtaining the user input via a user interface using audio playback controls re-mapped to control playlist creation.

7. A method as recited in claim 6, further comprising communicating between a client device having the playback controls and a computer system with a database storing at least part of the data collected from users.
