Jason has put together a mashup (ah, that term seems so old and dated now)  that combines twitter, blip.fm,  and the Echo Nest.  When you Blip a song, just add the tag #recsplease to the twitter blip and you’ll get a reply with some artists that  you might like to listen to.

This is similar to recomme developed by Adam Lindsay but recomme has been down for a few weeks, so clearly there was a twitter-music-recommendation gap that needed to be filled.
