Echofi helps you find artists on Spotify that fit your tastes
Echofi is a simple web app that uses Spotify’s API to find music that’s more relevant to you. Simply search for an artist that you like, and Echofi will launch your desktop app with a song by a similar artist. You can then give the song a thumbs up or down using Echofi, and another song will be started for you. It’s kind of a Pandora-esque feature using Spotify.
