I have a confession: when I listen to these songs, I picture myself in some sort of ending montage on my favourite television show or movie. I could definitely (and most definitely do) lie in bed with headphones and listen to this entire mix without moving. A lot of these songs came from movie or tv soundtracks, and some I just think would be perfect in a soundtrack of some sort.
Pop the popcorn and enjoy.
