If Rebecca Black has any authority on the matter, then Friday is definitely the time to "get down." Whether you're getting ready to party with friends or just excited at the chance to veg out and sleep in, feel-good music is the only way to go on a Friday night. Because we know that everybody's looking forward to the weekend, we put together 20 of our favorite energetic tunes by Calvin Harris, One Direction, Nicki Minaj, and more. And, of course, no Friday-themed playlist could possibly be complete without "Glee"'s cover of Rebecca Black's viral sensation.
So, tell us -- what songs are we missing? What's on your weekend pump-up playlist? Leave your best suggestions in the comments below or tweet @HuffPostTeen!
