I love Pandora specifically because if you put in something as specific as a song it would recommend other similar songs.

And not just similar in terms of year genre or artist, but similar in terms of how they sounded. And you could even open the details and you could see how their music staff and genre experts had tagged each song. And that was really cool.

Stuff like “hand claps”, “breathy vocals,” “virtuosic acoustic instrumentals”, etc.
