Tap plays song and loses current playlist ..SO annoying

[Unquenchable]

I agree with everything that the OP has said, and I can't believe this is the only post on the issue. I find it far too easy to accidentally touch the screen, especially when walking, and this will delete the playlist that I've been building up.

The desktop version has the option to set Enqueue as the default action and it would be nice if it could be added to the mobile version.
