Mine would personally be Owl City for some reason. Still dont know why
The tellatubbies song reminds me of Clank 
There is this one track in Snow White & The Huntman that sounds almost exactly the same as a track from Going Commando. I'll look for it 
Chasing Cars by Snow Patrol and Hey You by Pink Floyd (reminds me of Azimuth)
Chasing Cars by Snow Patrol.
You mean like:
''If you lay here, if you just lay here. Would you lie with me and… just forget the world?''
That is kinda Ratchet & Clank idd.
