My point is this: I am currently away from home, but not away from my music. Last.fm is seemingly a Pandora knockoff (for those who don't know Pandora.com, its awesome), but Last.fm keeps track of what music you listen to through iTunes, and logs your preferences. You can listen to streaming radio of music it recommends for you (which is not quite as good as Pandora, yet), but you can also listen to streaming radio of music you own. So I am now listening to my music, just from an online database that knows which tracks I own.
Technology. Pretty cool. Per usual, thanks for wasting your time with me.
