What is your favorite song(s)? Please help

[/Kay//]

For my yearbook class I'm helping (or trying to help) make the video version of the yearbook.
We need (appropriate) song ideas of any genre for the background music.
I would appreciate as long of a list as you'd be willing to talk your time to type, since I already made a folder of lots of songs so I may already have a lot you guys like.
We're looking for mostly songs that are upbeat or make you happy, since we don't want the people who are leaving to cry. Any songs are appreciated though.

Thank you for reading

Also tomorrow is the last day my teacher would allow me to add songs to it, so I'd appreciate answers as soon as possible. I have quite a few already so I understand if nobody has any favorite songs or if they have more important things to do.
