US- the songs are pop and nice. However,one can fall to sleep hearing them. They do not have the talent like Mariah, Whitney and Celine. No Rap music and No hiphop music, No sexy singers like Jen Lopez, No funky divas like TLC and Destiny's Child. Besides Billie Piper is sexy .
American rock is nonsense.
Because they have a more unique music style. Unlike U.K. who's music is known for boy band, girl group or losers like Robbie or techno crap music. US is better. That's the way music is. I have heard of all those you mentioned.
