For the last one, I usually go with John Mayer's songs, more specifically, the songs from his Continuum album. Some of my favorites include "The Heart of Life", "Belief", and "Dreaming with a Broken Heart". Aside from these, I also like listening to the rest of the songs in the album. John Mayer's not one of my favorite singers, but I do enjoy listening to his songs from time to time.
Have you ever felt that way - like there are times when you don't want to listen to a particular type of song, but other times, you find yourself wanting to listen to them again and again?
