I have over 60 songs on my home workout list, 40 on my gym cardio list, 28 on general gym, 15 on spin room. I like to do cardio to upbeat songs - not necessarily songs I'd listen to normally but so long as the beat and tempo are good, I can work with it I also include slower songs for warm up and cool down. I also stagger my list so that really good songs come on at the time I'm usually struggling. But I do change it around regularly because otherwise my mind and body know what's comming next!
