Currently for me it would have to be these in no particular order: Home Life- John Mayer-(I could listen to any of John Mayer's music and enjoy them)
Upside Down- Jack Johnson- (Again any of Jack Johnson's music is relaxing enough to listen too)
Run Away- Staind
Fireflies- Owl City
Little House- The Fray
Chamber The Cartridge- Rise Against
Not Alone- All That Remains( Every song off of the fall of ideal's album is awesome)
Guitar Sound- Ronald Jenkees
I don't really have a particular main type that I listen to. I listen to everything including classical music.
