How many gigabytes of metal do you have?

I once had 20 gigs, 14 of it downloaded about 6 gigs actually bought. I can't always afford to buy CDs all the time.
 
1500 ish CDs, about the same in tapes and demos, about 50 Vinyll.

MP3's ? the most frequently played cds get ripped onto the MP3 player, so I guess 20gb at any one time.
 
I use iTunes for most all my listening any more. I migrated from Musicmatch/Winamp/Media player. iTunes runs the smoothest, hogs less memory than most, and lets me keep track of my podcasts, online radio links etc.
