I tried to find "songs" but couldn't. How do i find "songs"? How do I delete an individual track?

Close the current song from the Menu. Then use Long-Touch on a song icon

What could be the issue if nothing happens upon the long touch?

Hi Conney, it's possibly a bug. If it doesn't work to use just the tip of a finger and hold very still for 1 second, please try shutting down multitrack fully by bringing up the task bar in iOS and swiping multitrack away. Then start multitrack and try the long touch again. If long-touch now works, it's very possibly a bug. If it still doesn't work, something else is wrong with the system because multitrack simply uses the 'long touch gesture' of iOS to trigger the edit mode. Please let us know how this turns out
