I so, so agree. The music choices are dire.
If it's because the producers are trying to play to a 'younger audience', then why don't they give that audience more credit?
Many of the 'younger people' of my acquaintance will hear a piece of music on the telly, and - if they like it - go off and search for it on t'internet. They don't always expect to hear something they already know.
(you can turn all of that around for us oldies, who occasionally hear music that we like, but don't know, and go out to look for it).
As an aside, DD and I almost had a 'Keystone Kops going through a door' moment after hearing Kellie and Derek's Argentine Tango music on Dancing With the Stars.
That's the phenomenon I'm talking about!
