I cannot count how many times I've done this (granted, I'm clumsy).
Using Touch to scroll through artists/albums/stations to create a Playlist, I intend to press & hold an item to Add to Playlist, but I end up PLAYING that item, which wipes out my newly created Playlist.

Safety Feature:  If a Playlist exists, or an item is already playing, have a pop-up screen to ask me "do you really want to Play this item which will wipe out your current Playlist?"

Or, an optional Safety feature (ON / OFF) in the Settings that will NEVER play an item from a finger touch and instead will only launch the Context Menu (which already includes Play and Play Next).
