Duran Duran and No Doubt
I enjoy (also with the ingestion of alcohol) the fine music of John Dowland (The Randy Rhodes of the 1500 century).
Especially the galliards.
Also Mozart and Arnold Schoenberg.
To many to mention ha ha! I think most metalheads appreciate most music with loud guitars ;-) I mean it´s hard to say what's not metal enough with old bands who actually contributed to the birth of metal, I listen a lot to deep purple, nasareth,the who etc.. I also listen to my fair share of Oi ! and Punk, and sometimes I´m in the mood for Johnny Cash! ha ha I love good music no matter what genre as long as it is someone actually playing the instruments sampled shit like hip-hop and trance I cant stand!
