You know the first reason ;)
Iunno what you're into, but The Agonist - Thank You, Pain is probably one of my favorite metal songs to play.
I have spent much time browsig the catalog on RBN and I must say ther are some very talented autors out there. You guys have put alot of time and effort into your craft and for that I commend you. Keep them coming guys/gals. Good work!!! :-)
You might like this band's stuff. Their songs are only 80 points too.
Strikken - The Final Act
Judas Priest or Anthrax will do.
My wife and I like the All That Remains songs on RBN, but they're more modern-sounding. Mystakin and Bluefusion also have some darn good instrumentals. Though they're alternative, maybe you should also check out Drugstore Fanatics, who are very quality.
If you like prog metal, Andromeda is a pretty good bet. If you play guitar it's melodic, if you play drums it's technical, and if you play keys well, good luck.
