Ok i have been downloading music soundtracks and stuff like that for a while (All legal, soundtracks are really cheap on official sites and have better quality than those fake ones on the internet, trust me)
And i have a good collection of epic (E: Lord of the rings) music that could be used in flash or could give ideas to you:
The Battle - The Chronicles of Narnia - Awesome piece, its really really good- by Harry Gregson Williams
The Battle of Kerak- Kingdom Heaven- You can hear this tune in Neenja parts 3 and 4- also by Harry Gregson Williams
Blood Ravens Aproach (this is actually free)- Warhammer 40k- Jeremy Soule
Battle Forest Boss - Neverwinter Nights- very good- Jeremy soule
Main Theme- Guild Wars- Jeremy Soule
Mission 18:Zero-Ace Combat Zero- Master Piece- I dont know who
Helms Deep- Lord of the rings:The Two Towers
The Hornburg- Lord of the rings:The Two Towers
The Elf parade (shorter version of The Hornburg)
Battle Heroes (AKA A hero falls)-Star Wars Episode III- John Williams- MUSTAFAR! YEAH XD
Return of the Jedi End Theme- Star Wars Episode VI - John Williams - The best victory song to be created
Chariots of Fire-Chariots of Fire- I Dont Know- Well Known music, not epic actually but really familiar.
(Thats the music they use when someone runs on slowmotion on a Marathon or something like that, never seen the movie though)
I hope this is helpful to you Animators, and gives ideas to you composers.
NOTE: Most of these songs are trademarks of their respective movies/games
thanks
