Seems like a good way to validate it would be to have everyone play the same set of songs. Then to tell if the predictions work, see if it can find each different song each individual plays. I hope the design wasn't as bad as you say.

Reading into it more, the second most predictive feature was a context variable. That is, identifying features of the specific song.

I think this one gets a thumbs down from me.
