An item on my iTunes wish list has been keywords [sub-genre] akin to iPhoto's keywords. My main music of choice is jazz which begs for sub-classification; but using custom genres in iTunes would be numerous and unwieldy--jazzintrumentalhardbop...jazzsvocalcontemporaryfemale...and on and on. I'm considering using the new 'beats per minute' feature in iTunes 4 to code my own keywords since I doubt I'll ever use this tag as it was intended. Something like this: Key Defined....Instrumental....Male[s] Vocal....Female[s] Vocal....M/F Duets and Group Vocal Vocal^.................-....................10................... 20 ................... 30 New/Chi*.............1....................11....................21 ................... 31 Swing...................2...................12....................22 ................... 32 Bebop..................3....................13....................23 ................... 33 CoolCoast............4....................14....................24 ................... 34 Hardbop..............5....................15....................25 ................... 35 Latin....................6....................16....................26 ................... 36 Fusion.................7.....................17...................27 ................... 37 Contemporary.....8....................18....................28 ................... 38 SongBook$..........9....................19....................29 ................... 39 ^-Works with any genre *-New Orleans and Chicago styles $-Film, theater, Standards with jazz genre I can sort on the BPM column and quickly go to all my bebop male vocal tracks [13] or instrumental west coast cuts [4]. And this code matrix is easily memorized. Or I could use the Genre tag for the broad classes [swing, bebop, etc] and define the key codes descriptively--'Hot', 'Cool', 'Blue', etc. Some might simply want to use 1 for female and 2 for male and 3 for mixed singers to sort their music by just those criteria. This scheme also can be utilized by smart playlists--a constantly updated list of all your jazz genre, latin style, mixed vocalists from the 1960s if one was so inclined. I believe some balance between genre and a short key code list can greatly enhance iTunes classify and sort capabilities. -------------- Tony
