I don't quite understand the operations or signals you mentioned, could you explain it with more details please?

You could potentially use one association from User to Music. User can then invoke operations on Music. If you had interacting state machines in User and Music, or if the objects ran on separate machines, you could send signals instead. Music could have what are called signal receptions, which look almost the same as operations. (Although I just noticed that listenTo() and collect() operations don't make sense as operations or signals. You seem to have something in a netherworld between an analysis model and a design model.)
