I think these alternatives would fit in best with an action/romantic movie, so i would choose these songs..
*Opening credits : AC/DC - She Likes Rock N' Roll
*Fight scene : Airbourne - Hellfire
*Romantic scene : Hmm, this one is hard.. maybe, 3 Doors Down - Here Without You, only song that came up to my head right now ;D It also depends a lil on how the scene is, if it's a sex scene for example then i would maybe choose another song lmao xD
*Your funeral : Takida - Curly Sue, or, Staind - So Far Away
*End credits : Nomy - This Heart Of Ice, and, Saving Abel - New Tattoo ( In the end it use to be more than 1 song so i would choose these 2
I would choose the lil more calmer song first and then the song with a lil more rock n' roll in it will fade in, cuz it seems like the movie ends with my funeral lol xD )
Btw.. these bands are fuckin awesome so if u've not already heard them, listen to them! =) And if u have any questions about other awesome rock bands like these, u can always ask me cuz i know a lot more great rock bands! Maybe someone can make a topic about music or something, i'm too lazy xD
