Used daily while doing grad work at Starbucks

I have had this app for a long while now, and I still use it. I used to use it only to help me sleep on the plane. However, I now use it daily while researching and doing homework for grad school. If i can get my hands on a nice pair of noise-cancellation headphones, Ill be set!
