My stuff is on a loop and plays the same 70-100 songs in a row until I switch it out with something else.
But it will be something like Rage, Ice-Cube or NWA, AC/DC, Two-Chains, Alice in Chains, etc.
I also tend to get on a Zepplin or Sabbath kick and, go through 3-4 songs at a time.
Then there are the days I get a little crazy...especially with cardio work and will listen to Sinatra, Bishop and the Rat-Pack...Stevie Wonder and Elton John.
My tastes are eclectic!
