Not sure if taste profiling via Pandora will really fit the art market as is Art.sy's goal. Eclecticism tends to win over similarity and some collectors simply obsess over a single artist or period. But they have some superstar backers. Also, they are hiring ;)
This sort of leaves an opportunity somewhere in the middle I think, between Etsy and Art.sy, in the $1000-$10000 range of purchases for young professionals just getting started. Curation will be key for that demo.
