Abstract

The present invention provides a method of and system for browsing of music. In an embodiment, a method of browsing recorded music comprises steps of: selecting a song from a library; playing at least a portion of the selected song for a user; while the portion of the selected song is playing, accepting input from the user, the input comprising an indication of the user'"'"'s enjoyment of the at least a portion of the selected song; repeating said steps of selecting, playing and accepting to generate a sequence of song portions; and creating a record comprising an identification of each selected song portions and the indication for the song portions.

Claims

1. A method of browsing recorded music comprising steps of:

selecting a song from a library;

playing at least a portion of the selected song for a user;

while the portion of the selected song is playing, accepting input from the user, the input comprising an indication of the user'"'"'s enjoyment of the at least a portion of the selected song;

repeating said steps of selecting, playing and accepting to generate a sequence of song portions; and

creating a record comprising an identification of each selected song portion and the indication for the song portion.

2. The method according to claim 1, further comprising generating a playlist from the record, the playlist comprising identifications of the song portions in the record that were enjoyed by the user, and playing the entireties of songs in the playlist.

3. The method according to claim 2, further comprising interjecting new songs into the playlist while playing the entireties of the songs in the playlist, wherein said songs are selected to be interjected based on the indications received for the songs in the playlist.

4. The method according to claim 1, further comprising ceasing said playing the at least a portion of the selected song immediately upon the user making the indication.

5. The method according to claim 1, wherein each song of the sequence after a first song of the sequence is selected based on the indication for at least the previously selected song.

6. The method according to claim 1, wherein each song of the sequence after a first song of the sequence is selected based on the indication for a plurality of previously selected songs.

7. The method according to claim 6, wherein the indication for each song of the plurality of previously selected songs is weighted accordingly to position in the sequence.

8. The method according to claim 1, wherein the library includes extracted audio parameters and metadata for each song.

9. The method according to claim 1, wherein the library includes two or more different selected portions of the same song.

10. The method according to claim 1, wherein the at least a portion of each selected song is limited to a determined duration and the determined duration is adjustable by the user.

11. The method according to claim 5, wherein the library includes extracted audio parameters for each song and wherein each song of the sequence after a first song of the sequence is selected based on a comparison of the extracted audio parameters for the selected song to the extracted audio parameters for the previously selected song and the indication for at least the previously selected song.

12. The method according to claim 11, wherein the comparison is performed by computing a distance between a vector of the extracted audio parameters for the selected song and a vector of the extracted audio parameters for at least the previously selected song.

13. The method according to claim 11, wherein the selected song is selected to minimize the distance between the selected song and one or more previously selected songs for which the indication is positive and to maximize the distance between the selected song and one or more previously selected songs for which the indication is negative.

14. The method according to claim 11, wherein the selected song is selected according to whether it is within a determined percentile of distance to one or more previously selected songs.

15. The method according to claim 11, wherein each of a plurality of the selected songs is selected according to whether it is within a determined percentile of distance to one or more previously selected songs and wherein the determined percentile of distance varies over time.

16. The method according to claim 11, wherein the library includes metadata for each song and wherein each song of the sequence after a first song of the sequence is selected based on the metadata for the song.

17. The method according to claim 1, wherein the record further comprises the amount of time while the portion of each selected song was playing before the indication for the song was received.

18. The method according to claim 5, wherein two alternatives are computed for the selected song before the indication is received from the user and then the at least a portion of the appropriate one of the two alternatives is played immediately after the indication is received.

19. Machine executable code stored on a machine readable storage device for performing a method of browsing recorded music, comprising steps of:

selecting a song from a library;

playing at least a portion of the selected song for a user;

while the portion of the selected song is playing, accepting input from the user, the input comprising an indication of the user'"'"'s enjoyment of the at least a portion of the selected song;

repeating said steps of selecting, playing and accepting for a sequence of song portions; and

creating a record comprising an identification of each selected song portion and the positive or negative indication for the song portion.

20. A system for browsing music comprising:

a library comprising a plurality of entries for songs to be browsed, each entry comprising identification of at least a playable portion of the song corresponding to the entry and information about the song;

a player for selectively playing the portions of the songs;

a user interface for accepting input from the user while a portion of a selected one of the songs is playing, the input comprising an indication of the user'"'"'s enjoyment of the selected song; and

a song selector that selects a next playable portion of a song from the library to be played next by the player based on the indication accepted from the user and based upon the information about the songs in the library.
