How big is yours?

Did the subject get you to look?

My iTunes Library size:
8479 songs - 27 days, 20 minutes, and 2 seconds - 37.77 GB

1346 tracks added in the last month alone. (Blame Nicole for most of those.)

Just got done sorting all of the new Nine Inch Nails stuff that got added, and then promptly went and bought most of it (used, of course).

Nicole and I share the iTunes library on a disk with permissions disabled. This allows us to both add music to the library and see it in our own separate user accounts (Mac OS X 10.3, by the way). The iTunes Library is shared, but we have our own preferences for the iTunes app itself. We use the grouping feature to separate tracks by username. It works pretty well, but the downside is that only one of us can really rate music. And, since I already rate everything, Nicole misses out.

Breaking it down a little bit further (I'm a bit obsessive about this, can't you tell?) yields these stats:

38 1-star songs
594 2-star songs
2225 3-star songs
1790 4-star songs
678 5-star songs

5199 AAC encoded tracks
3279 MP3 encoded tracks
1 Audible encoded track

692 tracks purchased from the iTunes Music Store (mostly by me)

251 songs have been played in the last day
2358 songs have been played in the last month

Smart playlists are cool.
