It seems to be a common trend of rock for big mountain. Rap/Reggae for park skiing. And a softer reggae or something easy on the ears for powder. It also appears that you are new to newschoolers and maybe just trying to get some comments up under your belt. I don't blame you everyone here did the same when they first signed up. Being that you want to do all three main types of skiing in a single edit you pretty much have all main genres making it very difficult to single out a song that you might like. e.g.(i do not know you or what rap artists you might like; 'A tribe called quest' or 'Eminem'? Very different rap artists. Some Silverchair is always good for big mountain. songs: Freak, or Tomorrow! 'Going up the country' by 'Canned heat is a classic song. You could do a pretty sweet exploration clip with a bit of powder, big mountain and touring in that i recon.
Good luck with your edit if you actually do it. Please link it to me when your done.
