It depends for what mood I'm in and the time of day.

If it's earlier in the day, I'll alternate between country and my "Ultimate Playlist" I designed for road trips and relaxing in the backyard.

Sometimes classic rock is good, but not all the time.

If it's late at night and I need to go to bed soon I'll listen to comfort music like Enya and Matchbox 20.

If I have a big project or cleaning I listen to my Ultimate Playlist or Workout Playlist.

What I suggest is to invest in an iPod and a bluetooth speaker if you can invest in it and you think you can use it. (this is my speaker, it's amazing and perfect for indoors and outdoors: Kmart.com)

Then on your iPod create multiple playlists for your different mood. I have several playlists, Ultimate Playlist, Country, Country Party, Workout, Skrillex, etc Some of them are for different moods, and some of them are single artist that I listen to frequently.
