Well, when I was younger,I really enjoyed listening to rock.The loud rhythm and the cool appearance of the band members really amused me.But as I grew older,I found myself less enthusiastic about rock music, mainly because it does not challenge my listening skills and also that there are always a lot of repetition between different rock songs,which makes me feel bored somehow.So now I like jazz the best.It is a sophisticated music,with rich layers of feelings, and I can really feel relaxed when jamming to jazz.
