I've never used this site before, so I can't comment on how it used to work. This interface is not at all intuitive though. - click a play button on a song - music starts playing - click a different play button - nothing happens - click pause - music stops - click a different play button - nothing happens - click play - first song continues playing Steps to get a second song to actually play after you've got a first…
