“Hopefully Rap music follows the downward trend”
Don’t hold your breath: as long as there are talentless “musicians”, we’ll always have rap, and I’m not foreseeing a major shortage of talentless “musicians” any time soon.
The problem is “rap” has crept into more mainstream music. Nothing worse than hearing a decent song only to have some stupid rap in the middle of it.
Rap is cheap to produce, throwaway flavor-of-the-month “artists” the record companies don’t have to pay much for.
I think the taste expectations of the audience has something to do with it too.
Kids who want something better can get all they want from the internet, mostly free of charge.
Yes it takes a tiny amount of intelligence and capital to download songs from the internet onto your mp3 player.
For those who can't come up with those, there's the radio.
Thus, you see the broadcast bands aiming their content at the lowest common denominator, the lowest of the low, the worst of the worst.
It's true for TV too.
