I have close to 1000, pretty much all 'purchased.' I do have a handful of them that are 'ripped' from borrowed copies and downloads, but compared to the purchased ones, that number in miniscule (like maybe 10 to 15)
Now, I put purchased in quotes for a reason: I worked for nine months at a Virgin Megastore, during which time i was able to get up to 5 promo CD's a week (we got paid crud wages and no benefits, so free CD's were our benefit), and i took home five nearly every week, mostly due to my varying tastes in music. My collection before starting was 350, when I left, it was 700. between the promos and my numerous purchases with discount, I doubled my stacks in less than a year (paycheck? what paycheck?).
Since then I've done small bits here and there... getting pickier and pickier. I have some gaps in genres that I'm trying to fill as well. Good jazz for example. I have a TON of classical. Also starting to build the R&B selection. Just about the only things I don't listen to are gansta rap and death metal. I'll listen to anything else... literally. I have a CD of the Gyuto Monks chanting, all the way to Metallica, Snow Patrol, The Cure, Madonna, Beethoven, Glass Tiger, Josh Groban, Barry Manilow (shut up, I love him), Gaelic Storm, and a variety of world music as well. There's also a lot in between...
And if anyone wants my Kenny G cd's (not really into him anymore, but don't have cases, just disc and booklets, so selling them would be difficult), PM me... I'll send them to you for free... yes, the originals.
My CD's are in six of those big black books, alphabetized by artist. I also have a computer program that has all the info in a database... if you want a good shareware program, Readerware is excellent (they have an Audio version and a Video version as well).
