In the time I've been a RAFian, other RAFians have recommended to me much music and many bands for my listening enjoyment.
I feel like paying it forward, so to speak, by making a shortlist of bands that, pre-RAF, I'd not even heard-of. Feel free to do the same in comments, if you like.
Lordi - Awesomesauce on cheese fries in the back of a humvee on the moon. Metal.
Basshunter - this music is HAPPY distilled into longitudinal compressions and rarefactions of air.
Nightwish - I do not have the words for how awesome they are. Symphonic metal.
Ayreon - Coolidge. End of story.
Infected Mushroom - I'm still getting used to the idea... :D
Dredg - twenty-seven kinds of epic, whether it's the album or the live-acoustic version.
Freedom Call - where Triumph and Happy meet and spend the rest of their lives riding off into the sunset. Power metal.
I know many of these may not be to your individual taste, but please don't write off one band just because you disliked another band on this list, because none of these really even fall into the same genres as the others.
Have a happy weekend, dearlings! I'll see you about. :)
