It's only pop music. Either you like it, or you don't. There's far too much snobbery when it comes to this stuff IMO.
FTFY
Billy Connelly summed it up perfectly I think. He said there's music you "get" and music you don't. If someone likes it then it can't be bad music.
Like Connelly I don't "get" Jazz. I suppose there are enough Jazz enthusiasts out there to make me think there must be something in it but I doubt I'll ever understand what it is. I "get" rock music.
I'm a HUGE fan of Bowie's early material...I think a large chunk of today's pop/rock owes him a huge debt for laying some amazing foundations. He was an incredible talent.
If you like his 80's/90's stuff then you'll most likely like everything he does from now on, including this new single.
My advice to any Yoof is to ignore this and listen to his 1970's material. I think non-prescription drugs are the force behind much great music. I expect Bowie went to rehab and then came up with the "Little Drummer Boy" idea.
Look what happened to Lennon/McCartney after they "de-toxed". Frogs and bloody Polar Bears.
