Re: If you work out..
Agreed. I have everything on my running playlist from Metallica to Arcade Fire to Eminem to The New Pornographers. I am not a big rap fan but Eminem's "Lose Yourself" is a great work out tune.
Same. Lot of classic rock, Stones, Zeppelin, Humble Pie, Aerosmith, Van Halen, Faces, Nirvana, Pearl Jam, Nickelback, Bush, Nine Inch Nails, Radiohead, Chili Peppers, Smashing Punkins, Toadies, Buckcherry; some rap/hip hop like DMX - Lose My Mind; Lil John and the East Side Boys - Get Low; DJ Kool - Let me Clear my Throat, etc. . .
The common element in every song is that the pace and the beat (or memories associated with the song) can actually cause an adrenalin boost and get you over that "one more rep" or "one more set" or "five more minutes" hump, which is the area where you can really do some good. . . .
