Tru, I own Thiel 1.5s and a REL Strata III and put in the Bob Marley box set disc 4 right after my other two favorite albums when I got them. Sent shivers up my spine. It's not rap but reggae leaves a bad taste in most audiophile's mouths too (I get made fun of for listening to reggae on my system on a regular basis). It's also not high-fidelilty considering when it was recorded. But, Bob's voice, the background singers, and the instruments sounded alive. One of my Alpha Blondy CDs is particularly well recorded. The little "pop" rap that I own also sounds great on them. Hope that helps.
BTW, I wouldn't even respond to anyone picking on your musical taste unless you need some stress relief.
