Piker.:-) I have 19377 tunes, the vast majority I've ripped from CDs. That's 52 days 11 hours 33 minutes of continuous music, without repeating a tune. Granted, a few of them were albums ripped as one track. DSOTM is one example. I think it's amazing that we can have all this available instantly.
I don't trust online music. It's too easy for the companies to suddenly say, sorry, your stuff isn't available. I've had that happen with books and stuff as well. Screw them.
But do you have any ABBA tunes?..... : )
