well I will love you guys forever if you get this awesome song...
Bronyfied - Fight for the Crystal Empire (ft. Cyril the Wolf)
"Awoken by H8_Seed and Woodentoaster" a possibility? And maybe "Rainbow Factory" to go with it? (I really just want "Awoken" though because it is awesome!).
"Between Fairytales and Happy Endings by Princewhateverer" would be awesome as well. That is like my all-time-favorite song by him.
"Long Way From Equestria by Mandopony and AcousticBrony" is also awesome but probably not 'rock enough', so to say.
"Never Back Down by The Aviators" is also awesome but I think they do say Daring Do's name in it.
"Shining Armor by Mandopony" would be awesome one. Also, 'Shining Armor' can easily mean 'Knight in Shining Armor' so shouldn't have any legal issues at all.
Thanks for your requests!
Well. I am hoping mostly for "Awoken". If I get that song on Rock Band, I'll play it all day... Heck, I am listening to it right now and been so for a while now XD. Shouldn't have no problems with it. It has no pony names in it and doesn't even mention ponies in it actually.
All of this talk is making me want to get Awoken for RBB though.... And I can't...
