You know that song you told yourself "They ain't gonna play that shit"...but they did.
Or that deep cut that is so buried in an artist's discography you sometimes forget about it...but they didn't!
Even a cover or special guest that comes out of nowhere that could only happen at Coachella.
Any moments that made you freak out when you heard a song you didn't expect?
Outkast - Tightrope (with Janelle Monae)
Pixies - Nimrod's Son
Beck - Que Onda Guero
