Hmmm...I'm gonna do a few (separated by artists) because I never have an "exact" favorite! But these are the songs mostly on repeat
1. I Don't Wanna Be Free - Markiplier
2. My Bologna, Another One Rides the Bus, Polka Your Eyes Out & Albuquerque - "Weird Al" Yankovic
3. Pearls - Sade
4. Fansong, Deththeme, Dethharmonic, Go Into The Water, Duncan Hills Coffee Jingle - Dethklok: Metalocalypse
There's definitely more, but...this is off the top of my head ;-;
