I think a cover of Metallica's Battery would kick ass.
Also a cover of Holy Wars (Megadeth) would be really awesome or Touch Of Evil (Judas Priest) because of the cool keyboards.
Heh, Nightwish indeed. Maybe song "Devil & The Deep Dark Ocean" 'cause it's one of the coolest songs of Nightwish imo. With Alexi-type solo and jaujau growls it would be cool. True Nightwish fans wouldn't like it, thought.
Oh, hopefully the don't record a cover of this Twisted Sister song. I really hate it. This song ain't heavy. But maybe the Bodom boys can do a heavy kick ass version of it.
But they should cover some death metal cover songs again, like Mass Hypnosis.
I think it`s much cooler when a band does a cover of a non-metal band/artist.
For example Amorphis - Light My Fire. It kicks ass man, and the album Graveyard classics from Six Feet Under fucking rocks!!
My wishes would be: Aha - Take On Me , Dire Straits - Money For Nothing,
