Apple Music store questions...

Not at a Mac (at work ) and can't buy anything anyway (not in the US) but I'm fairly sure Pink Floyd were there from the start.

 

The only thing that comes up for the Beatles is "In the Beginning" the Beatles & Tony Sheridan (and ones like "Arthur Fiedler & the Boston Pops play the Beatles")

Pink Floyd, on the other hand, has 15 cover art pictures up. Not all are full albums, but even on the full albums you can still buy songs individually (One of the great points about the Apple Music Store)

 

Same here, I feel you're pain.
Some Australian artists aren't on there, except Kylie M. who has spent so much time (and plastic surgery) overseas that she shouldn't be Aus anymore.
