Gimme all your lovin by ZZ top would be my first pick. Second would be Le disko, and then insane in the brain by cypress. Three goods songs I think will work well and on three different lists. Honestly for a list of 30 songs that is supposed to make everyone in the world happy it is pretty decent. I did not know all the songs so I listened to the ones I didn't know... yes yes even the country ones. I strongly encourage you to do the same if you haven't cause it might inspire you. However I do have one small complaint that I am surprised no one else had.. Stronger- Kanye West AND harder, better, faster, stronger by Daft Punk. Both good songs sure, but that's because stronger is harder, better, faster, stronger without the harder better faster. Both those artists have other good songs too so let Kayne keep stronger and give the Daft Punk fans another song since they probably want one anyways.
