Don't say everyone. Some people still have a taste in music.
And there's nothing wrong with modern rap and r&b or hip-hop whatever you want to call it.
That is the persons taste in music, and you shouldn't criticise them for it, where does it say a person can't like mainstream?
Most people like it because the media make it look and sound like the best music out there on the charts. Personaly, I like indie rock, classic rock, rap, and modern rock. The strokes is a good band.
I do like modern rap, and mainstream. But hey, thats just me.
I don't feel like searching the internet for underground bands that 'nobody' knows about just so I can say I don't listen to mainstream.
Don't judge people.
