Have you tried Gnoosic (http://www.gnoosic.com)? That is the one that works best for me.

I'm thinking of incorporating gnoosic (or something similar--haven't looked yet to see if they have an API) into Lagukan for recommending new artists. Mainly my work has focused on re-recommending songs you already know.

No, I didn't know about it, thank you!
