There must be quite a few music enthusiasts using Spotify who are also playing some instrument. So what about an app that enables easy use of Ultimate-Guitar.com together with Spotify? For example I play bass and often learn new songs by playing along with them. Now my practicing is often confusing since I have to find the song on Spotify/Youtube, then go search for the tab/chords, then start the song, then change to the tab again. A Spotify app would make this so much more convenient.
