This came out of a funny dinner conversation with some friends talking about discussing favorite musicians. Someone proposed that the musicians most likely to be spark interesting conversation were those that were unpopular enough to be "cool", but popular enough that someone else could have feasibly heard about them, and suggested that musicians with ~1M monthly listener count were the sweet spot. (Empirically, I think that's about 5-10x too high.)
Anyway, this tool should help you figure out which musicians make for interesting conversation. If you'd like to compare against me, my friend code is "uIrtZpcNPUZpikRlAVPg".
Sometimes it takes a minute or two to load artists - Spotify's API rate-limits pretty aggressively.
