I listen to rap mostly, my favorite album is Infinite by Eminem, and I listen to a lot of Royce da 5'9" freestyles. Other favorites of mine are Naughty By Nature (Treach had a sick flow and is one of the most underrated rappers), Jay-Z, Nas, and Lupe Fiasco.
Recently I've been getting into Elzhi, and Diabolic is good as well.
My favorite band is Sublime, followed by Rage Against the Machine.
I also listen to scores from movies (Titanic and Jurassic Park are two of my favorites, as well as The Lion King).
Metal (favorite subgenres: melodic death, symphonic, power, folk, folk/black), underground/alternative hip hop, Indie rock, classic rock, opera, a variety of foreign music styles (Arab pop and Kartavelian (Georgian) folk music are some of my favorites), house music, and blues, but I'll listen to anything that sounds good to me.
