I could just list the groups that I enjoy listening to, but instead, I'll suggest to you when a good time to listen to them is.
You are relaxing by the pool 
You are lounging around the house
You are excersicing 
You are throwing a party

You are mad, and don't mind getting a bit madder
You are driving around in your car
The lady (or man, whatever, it's all ok) friend is over
