Great stuff! I happen to really like all recommendations that came in for me.

Some suggestions: this pure social graph approach could be vastly improved for music recommendation by aggregating tags, à la last.fm, or adding music-related features yielded by some waveform analysis.

For instance, I typed in Tame Impala and got these results in this order: Real Estate - Girls - Beach Fossils - Toro Y Moi - Washed Out - Wavves - James Blake. The first three relate well to modern psych rock of Tame Impala, but then things get a little strange: two chillwave acts, one correctly similar psych/noise rock act and a dubstep/downtempo artist!
