I don't make 1 to 10 in music genres. I should do this (in order):
1. Hip-Hop/Rap
2. Metal
3. Rock
I listen to real hip hop music like Ja Rule, Jay-Z, 50 Cent, The Notorious B.I.G., 2pac etc.; I don't listen to crappy rap music like Soulja Boy Tell'em, the Stanky Legg song and other junk. In other notes, the rappers that I like sold over 20 million albums world wide.
Metal is good like Metallica and rock is good like Linkin Park. But the main music I listen to is R&B/Soul, Rap/Hip-Hop & Pop. No one can possibly hate an whole entire genre.
EDIT: In other notes, I commonly listen to Hip-Hop/Rap and rarely listen to metal and rock.
