I don't have any of those and probably won't. But a couple artists I'm not familiar with and may check out.

I don't understand the Adel thing. I love 21, to me Hello sounds like a reject off 21. And the 2nd song released to radio I can't even stand to listen to.

Madonna? I suppose radio doesn't equate to "good" but I don't remember hearing any of her songs on the Top 40 stations from that album.

Looking back, 2015 was actually a slow music buying year for me.
