i will do this at some point after the final release for this version but wouldnt it be better to have it as a prompt?
IMHO, the feature should be optional. The number of repetitions of a single track on the Now Playing List could be determined by user.
If a track was repeated more than twice (supposing 2 repetitions were allowed), user should be given a prompt:
"The track have already been played. Do you really want to play it once again
"
