Extreme metal (brutal death, black, dsbm/nsbm) is the ultimate litmus test for high testosterone.

I genuinely cannot fathom listening to rap/modern country, or being unable to at least get into entry level metal genres. No better music for gym, driving, or even laying around chilling than extreme metal. Burzum/dsbm for walking around outdoors or chilling in bed, suffocation/devourment/etc. for gym.
