See the below menu. The articles “a” is not required or appropriate in these cases.
Also “Play from this music” is awkward. It should be “Play this track” or simply “Play this music”.
" Add a music" is inappropriate. It should be “Add music” or “Add this track”. Track is more colloquially correct than music in these circumstances.
See also “Add from this music to the end of the queue”. The more colloquially correct would be “Add this track to the end of the queue.”
