What do you usually hear ?

Music is one of the possible solutions to relieve or to reduce stress. And the type of music you must listen to depends on you because not all people have the same preferred kind of music. It's up to you whether it's a piece of rock music, classical music, jazz music, reggae music, etc. as long as you think it sounds good in your ears.
