I'm not into any specific genres, but generally I like music with beautiful melodies, a nice fast-ish beat, and a good combination of major and minor keys. This can be anything ranging from classical, techno, pop, rock, metal, country, jazz, indie, dance, to folk. I am one of those people who doesn't give a shit about lyrics and can love music from any country and language. Also I am synesthetic and love it when music gives me intense feelings in my chest/stomach and various mixing impulses in my head.
A couple artists I enjoy are The Beatles, Nightwish, Modern Talking, Korppiklaani, MUCC, L'arc-en-ciel, Buck-Tick, Steven Universe OSTs, Rammstein, Cigarette Daydreams, SuG, Thornapple, Jack Strauber, Alizée, Voltaire, Hide, Alexander Rybak, and The Arctic Monkeys.
