When I was in college and only had time to read textbooks, I listened to a lot of music. Epsecially music that didn't have a lot of words and some music that didn't have words at all. I didn't really like classical music, so I sought out modern instrumental bands. I disvoered Explosions in the Sky which is my favorite instrumental band!
Some of my other favorite bands include:
Death Cab for Cutie
She & Him
The Civil Wars
Florence and the Machine
Here is another favorite! Boyce Avenue does a lot of covers and they're awesome!
