Yea but is it REALLY worth that? Discogs is an open market like ebay. Yes they want $560, but is someone really going to give them that? I'm only aware of that site because there was a bunch of albums called "edit crazy" by a local chicago DJ named Bobby D on a station that still exists today called B96 that you would likely only find locally. It was all mixed house music that I grew up with. 10 years ago you could still buy them for about $15, now there aren't any for sale. Luckily I have most of them on mp3 either by ripping what I had, or finding them on ebay.
Maybe I'm not old fashioned, but I can't fathom having to fumble through CD's to find the song I'm looking for. My mp3 NAS is somewhat organized (could be better), but I have a section for full albums, then I have categories for random songs like cover songs, comedy, mashups.. it's so nice to be able to just throw a folder, or a chunk of songs into a player, and just quickly flip through songs. It's also nice to be able to simply use windows search like all songs with *dance* in the title.
