The only question is did you pay for your couple of hundred Gigs of non-DRM music? If so, nobody cares. If not then you are basically a thief.
I stopped buying music for about 10 years because I was tired of getting screwed over. I'd buy a CD for $20 and get the one song I liked - and 9 others that were garbage. I ended up not even listening to the CDs because it was too much of a pain in the butt to put the CD on for that one song. When the iPod came out, I found I could use all those old CDs, by grabbing just those songs I downloaded. So I started buying music again. I figured if there were 3 songs on a CD that I liked I'd buy the CD. Then when the iTunes Music Store came out, I started buying even more songs (all those old one hit wonders I wanted). However I didn't like the DRM limit, so I still bought the CD if I figured there'd be 3 song on there I liked - so I was effectively paying $2-$4 a song for DRM free music vs. 99 for DRM free. When Apple came out with the DRM free music with EMI, I was ecstatic because now I would only be paying 1.39 for DRM free music. The DRM free music price has been dropped to 0.99 since that is the deal the music labels struck with Amazon. *great!*
Do I buy any of the music though Amazon? Nope. Not because I have any problem with Amazon, but my beef is with the record labels. They are trying to break iTunes by offering DRM-less music to them and not to iTunes. This is being done because they figure that if they can get 2-3 additional major players that they'll be able to re-instate stupid pricing schemes. When they want variable pricing it isn't because they want to offer us a wonderful deal on older catalogue music. It is because they want to screw us over on new music. So what do I do?
I play by the rules. If I listen to it I buy it. If I don't, I keep my money in my pocket. I am tired of reading about people stealing then claiming that they are taking the high ground. Truly taking the high ground requires sacrifice on your own part. So at the moment I am only buying from those who offer DRM free music on iTunes. I will not give one red penny (or 99 red pennies in this case) to the record companies. Apple with iTunes has been the biggest positive force for music in the past decade and I'll be danged (clean version) if I'm going to support those who would turn the clock back.
Believe it or not I am somewhat sympathetic to the record companies. It does take a lot of dough to find, develop and market talent. These companies have many expenses, and are having their product stolen. I'm not saying they are blameless, but they are not the evil soulless creatures those on slashdot make them out to be either. Like it or not they do serve a valuable purpose. I really don't think you'd like what would happen to the music industry without them.
Now I don't know if you've legally accumulated your music collection or not. If you have, great! I'm glad that you support the arts in such a meaningful way. If not - remember two wrongs do not make a right. If you are not willing to pay for the product provided, does not mean you have the right to benefit from it. Just imagine if everyone in the world acted in this way... I like the drawings you've prepared for this building, but I believe the fee you are charging is too high, so I'm just going to use the one's I've photocopied. *bam* no more engineers or architects. I like this software, but your licensing requirement are too strict so we are just going to make unlimited copies for ourselves. *bam* no more software developers. Your book was really good, but everyone just read the scan from the original manuscript. *bam* no writers. Just remember that it may be you who is getting screwed over one day. Treat others like you would like to be treated.
Sorry about the rant...
