While this is cool, I am not sure that it is at all helpful. I did my search for Hungry Lucy. It returned results for Hungry Lucy. What I would like to see is an option for related artists or songs. Maybe a way to do a related genre search. Links to Wikipedia or Sound Unwound articles would be helpful also. I guess my big problem is that there is nothing here to help me discover new music.
Now if I type in the name of an artist I have just heard of this does give me a fast way to sample the songs, and I almost always go to Lala for that now. This is a bit helpful, I just wish that it went a couple of steps further.
