Online site/shop for old songs.

Sup.
I find a lot of good stuff around the internet, but it's in bad quality so I don't want to sample this crap. I just thought maybe there is some good online store for those songs or something like this. Any ideas?

ebay is still probably the best place on the web for old vinyl to sample but Dusty Groove in Chicago somewhat fits the bill for what you're looking for.

Of course its crap, sampling vinyl remains king's choice. Because its smack dab off the original recording from the studio it was pressed.

All those mp3 sites I use them as reference and I sample it sometimes because the sound can be interesting, like Hank Shocklee stepping on records to get that sound type shit!!!
