How to Love- Lil Wanye
Look it up even if you aren't a rap fan. It is one of his few songs that if you listened to it the first time, you would never figure out the singer is a rapper.
Right now, I have three songs stuck on repeat in my head.
1: Whiskey Before Breakfast - Ramona Jones
2: Mountain Dew - The Stanley Brothers
3: Foggy Mountain Breakdown - Earl Scruggs and Friends
