Auto playlist generation with multiple seed songs
First Claim
1. A system that facilitates generating a playlist comprising:
- a media analyzer that receives a plurality of seed media items and obtains metadata corresponding to the plurality of seed media items; and
a playlist generator that receives the metadata obtained from the seed media items, receives at least one candidate media item and its corresponding metadata, computes a similarity value for each of the plurality of seed media items based at least in part on metadata associated with each of the plurality of seed media items and metadata associated with the at least one candidate media item, employs a preference function on the computed similarity values for each of the plurality of seed media items to compute a final similarity value for the at least one candidate media item, and generates a playlist based at least in part on one or more final similarity values.

Abstract
The present invention relates to systems and/or methods that generate playlist(s) for a library or collection of media items via selecting a plurality of seed items, at least one of which is an undesirable seed item. Some of the seed items are desirable indicating that a user prefers additional media items similar to the desirable seed items and others are undesirable indicating that the user prefers additional media items dissimilar to the undesirable seed items. Additionally, the seed items can be weighted to establish a relative importance of the seed items. The invention compares media items in the collection with the seed items and determines which media items are added into the playlist by computation of similarity metrics or values. The playlist can be regenerated by adding desirable seed items to the playlist and removing media items from the playlist (e.g., undesirable seed items).

13. A user interface that facilitates playlist generation comprising:
-
a media library pane that displays information about a media collection and adds and/or removes selected tracks to and from a playlist; and a playlist pane that displays the playlist, the playlist being regenerated by a playlist generator on each addition or removal of selected tracks and other tracks similar thereto and being a function of the plurality of added tracks and removed tracks;
the playlist generator calculating a final similarity value for one or more candidate tracks by way of using a preference function to aggregate calculated similarity values for each added and removed track, and determining if a candidate track will be included in the playlist based at least in part on the final similarity value. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. A system that facilitates generation of a playlist comprising:
-
a data store that maintains a collection of one or more media items and metadata corresponding to each media item; and a playlist generating system that receives a plurality of seed media items and automatically generates and/or regenerates a playlist for the collection according to the metadata associated with added or removed seed media items to effect generation of a new playlist that corresponds to the added or removed seed media items, the playlist generating system determining a final similarity value for one or more candidate media items based at least in part on a preference function that aggregates calculated similarity values for each added and removed seed media item. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)

29. A method that facilitates playlist generation, the method comprising:
-
computing a plurality of similarity values between a plurality of seed media items and a candidate media item; multiplying each of said plurality of similarity values by associated individual seed media item weighting factors; aggregating the multiplied similarity values into a final similarity metric; automatically generating a new playlist by adding or removing candidate media items most similar or dissimilar to the plurality of seed media items, respectively. - View Dependent Claims (30, 31, 32, 33, 34, 35)

36. A method that facilitates playlist generation comprising:
-
displaying a collection of media items; selecting a desirable seed media item from the collection of media; adding the desirable seed media item to a playlist; automatically regenerating the playlist based at least in part on metadata associated with the desirable seed media item, the playlist selectively including similar media items from to collection of media items, whereby the similar media items included on the playlist are automatically selected based on similarities to the desirable seed media item; displaying the playlist; selecting an undesirable seed item from the playlist; removing the undesirable seed media item from the playlist; and automatically regenerating the playlist at least in part by employing a preference function to compute a final similarity value from a plurality of similarity values based on metadata associated with the desirable seed media item and the undesirable seed media item, the playlist selectively including media items similar to the desired seed media item and selectively removing media items similar to the undesired seed media item. - View Dependent Claims (37, 38, 39)

40. A method that facilitates playlist generation comprising:
-
displaying a collection of media items; selecting a desirable seed media item from the collection of media items; adding the desirable seed media item to a playlist; generating the playlist based at least in part on metadata associated with the desirable seed media item, the playlist selectively including similar media items from the collection of media items; displaying the playlist; selecting additional desirable seed media item from the playlist; adding the additional desirable seed media item to the playlist; and regenerating the playlist by automatically adding media items that are similar to the additional desirable seed media item based at least in part by utilizing a preference function to compute a final similarity value from a plurality of similarity values based on metadata associated with the desirable seed media item and the additional desired seed media item. - View Dependent Claims (41, 42, 43)
