When I work out, I tend to listen to some intense music to keep me going! On a regular day, not working out, I listen to more chill music so it's a total change of pace for me when I go work out and listen to music. On my playlist I always include:
Linkin Park (any song, really)
Hollywood Undead (again, any song)
Afrojack - Bangduck
Bloody Beetroots - Warp 1.9
Afrojack - Pon Di Floor
Designer Drugs Datamix mixtapes (1-9)
Tiesto's ClubLife podcast (any of them - subscribe via iTunes)
Lil Wayne's album - I am not a human
3OH!3 album "Want"
I don't have an actual playlist, I usually just decide what I wanna listen to as I start, each time it's different or just on shuffle. Hope I gave you some good ideas though!
