While listening to my Playlist there is no way to remove a song that is being played from my Playlist.
There is also no way to go to Playlist and 'search' for it. So if you wish to exact your Playlist you have to remember what songs you don't wish to listen anymore, or write it down somewhere, and then just go to your Playlist and scroll through hundreds of songs until you find it... So, if I'm cycling and run into a song I don't wish to have anymore, it's very complicated after you took off the "-" button. Can't find a reason why. Just put an option for "remove this song from Playlist". Why, on earth, not?

Thanks
