Shuffle between two or more playlists

[hehe123sausage]

I think you should be able to shuffle between multiple playlists.

My playlists are usually made for specific genres of music and I think the abillity to shuffle tracks from multiple playlists would be a great feature for Spotify.

For example, I have 1 playlist for Reggae, and one for Dub and I do not want these tracks to be in the same playlist. But I want to be able to mix these playslist into a shuffle.

Yes, also true for when you are parent and your children have their own playlists and you want to listen to a balanced proportion of everyone's playlists (for instance when you are travelling by car)

When you want to listen to a new playlist, I would like to mantain the actual music alive until the track finishes, without interrupting it. Like when you add a track to the current list, spotify permits you to listen until the actual track finishes and then continue with the new track.

The idea is to add a function to keep the music alive until the new list plays, in a regular way. The function can work for one time or by default in your system preferences.

Yeah. Pandora already has it to where you can do this with their radio stations.
