I rarely sweat it out without music cranked up — I even use music to motivate me before a workout. Although I mix it up and listen to different playlists, there are a few songs that really pump me up like "SOS," by Rihanna, "No One," by Alicia Keys, and "4 Minutes," by Madonna. These songs often make it into my workout playlists.
How about you? What are your top favorite workout songs?
