Sorry for my english... I used Google Translate 
Music Player Walkman - it is almost the only player without a button "delete currently playing track".
You just imagine the music collection on your phone for 500 + tracks, and listening to one of them - decide that it should be removed. For example, bored. The vast majority of players: delete the current (playing at the current time) track - almost 2 clicks, for a Walkman - need to go to a list of all the tracks look the same there, and be sure to follow that he did not play at the moment , because in this case it is impossible to delete a file...
I ask you to make an offer by the programmer (or a group of programmers) that they just added a button to the list:
Somehow, or in any other easily accessible place in the player.
Also, if you delete the track means available when playing another track - the name and picture of the current change to the name and image of the previous list, which should not be.
