Everything. And if I say everything, I mean everything. Here a short list during gym today:
(Alone during my gym session I listened to following):
Alan Jackson - Countryboy.... Parkway Drive - Crushed..... Bullet for my Valentine - Waking the Demon.......... Flogging Molly - Devils dance floor....... Jimmy Buffett - A pirate looks at forty...... Dub FX - Love someone...... Taylor Swift - Blank Space...... Carnifex - Die without hope....... Iron Maiden - Run to the Hills..... Jake Owen - Barefoot blue jeans night....... Shabboozey - A Bar song..... Luke Combs - When it rains it pours....... Parkway Drive - Sleepwalker........ Dropkick Murphys - The Seasons.......... The Notorious Big - Juicy....... Run DMC - It's Tricky........ Paris Hilton - Stars are blind....... Tupac - Changes.... XZibit - ...... ...
I listen to all genres, no genre is bad all good songs no songs bad. I never heard a song that was bad in my life.
Sometimes my gym sessions have all genres but most of the time it isn't all random. Sometimes I go to the gym and just listen to Metalcore, another time I listen to Country, Radio, ... another time the 90s HipHop or just random stuff.
