I've been collecting good songs for my videos, and have gone through my whole Ipod as well, here's what I came up with:
-Stay the Night by James Blunt
-Hello by Martin Solveig & Dragonette
-Jump! (glee version)
-Good Life by One Republic
-Scream if You Wanna Go Faster (for ride bits) (Geri Halliwell Version)
-Any Way You Want it/Lovin Touchin Feelin (glee version)
-Days of Summer by starkid
-I Gotta Feelin by Black Eyed Peas
-Hey Baby by Dj Otzi
-Something That I Want by Grace Potter
-Call Me Maybe
-Break out, Miley Cyrus
-Shake Your Tailfeather
-Glad You Came by the Wanted
I feel like it's good to have a lot of high energy songs, good for dancing, keeping the pace of the video up, etc, but also mixing in some nice slower ones for those awesome magical moments.
