I definitely vote to stay away from the "digital collection" feature unless it's an album you legally bought on iTunes or some other similar service. I consider VGMdb very sophisticated and wouldn't wanna see it have any kind of relation to the "piracy" sites a la #gamemp3s, Galbadia Hotel, or even the VGM Central hub. I mean sure, it's a known fact that pretty much everybody in the VGM community has mp3s of albums they don't own, but it's really hard not to. For a lot of the harder to find CDs it's either download them illegally or spend hundreds of dollars on it. I think it's best that stuff be left private. As in.. our own hard drives.
