Instrumental music in my opinion is the best kind. Though there are so many genres of music, instrumental music (best music making websites) is the best. It doesn't directly convey the meaning and let's you dwell on it, interpret it for yourself and gives each person a different emotion. It lets your mind wander, which in turn helps you relax as well as sort out soo many things going on in your mind. So personally I would recommend instrumental music of any kind.
