I’m a guy who has a lot of mp3s on his computer, the clear majority being ones that I bought the CDs for. The stats give me: 3,253 files. Now, that’s not all mp3s, as there are Winamp playlists and log files from EAC in there, but it’s probably safe to say it’s about 3000 songs. And actually, this is a low number, as I have about 20 more CDs that I’ve encoded but can’t get off the CDs because I overburned them and my drives don’t like that, so getting those encoded will have to wait until I can go back home and get the physical CDs.
If I remove all songs that I do not physically own, that’s 2,455 files, so call it 2,350 songs (roughly). However, this is somewhat skewed as some of these are legitimate downloads, either from Amazon or a copyright holder. Others are difficult to impossible to find legit in the US (read: the only sources are Hong Kong bootlegs, which is no better than getting it off a LAN or P2P), as some of them are songs from anime and video game soundtracks, a bit of J-Pop, some from the group Geinoh Yamashirogumi, and a soundtrack of a movie few have heard of that is now out of print and impossible to find.
So, roughly, I would say that i have probably 700 files that I shoudn’t, call it 30-40 cds. However, some of that would be easy–seeing as how things like symphonies and suites get files for each movement, while others would be much harder. I might have to import from CD Japan, if they’re even still available. I just found the Pi soundtrack on Half, so here it comes. And the rest I should get rid of. However, I don’t know if that’ll ever happen for all of it.
Now, does the fact that my legit music outweighs my copyright-infringing music by 4 to 1 justify completely what I have? No. Does the fact that I can’t find some of what I have justify it? No, but I doubt many people will care.
What’s my point? Not much of a point, other to say that some people do have many, many CDs which they take time to encode.
