Graduation is a very nostalgic occasion in one's life so it is better to have a nice theme for it:

1. The Journey by Lea Salonga (this broadway superstar who also dubbed the singing voice of mulan and princess jamsine for Disney tells us about one's very long journey that leads to a very bright end)

2. Graduation Song/friends Forever by Vitamin C (showcases the joy and sadness of meetng friends and moving on to the next level)

3. Breakaway by Kelly Clarkosn (tells about the story of a person who is ifnally uout of the shell and ready to face the challenges of the real world)

4. POwer of One by Donna Summer (Talks about unity and reaching one goal together)

5. I Can from the movie Do-Re-Mi (Tells us about the never ending friendship of three people no matter where they go to)

6. Will of the Wind by Jim Photoglo (Is about going with the winds of time to achieve one's goal)

7. Wind Beneath My Wings by Bette Midler (Talks about one;s gratitude for the firnedshipa nd sacrifices for the other throughout school life)

8. Clim Every Mountain from the Movie Sound of Music (Talks about the courage to go on with whatever fight after a certain school level)

9. A Hero Comes HOme by Idina Menzel which is also the sound track of the hollywood movie: BEUWOLF (Is a very hopeful song that somewhere along the way we gotta find that hero in our selves and that we should be where we wanna be, where we should be) 

Don't be such a jerk. Just say thank you and keep your crappy opinions to yourself.

Learning to fly, by tom petty

The future has arrived, the all-american rejects

Who says you can't go home, Bon jovi (and or with jennifer nettles)

Time of your life, Greenday

(don't you) forget about me, by simple minds

I'm gonna miss this, Trace Atkins

I'm alright, jodee messina

Carlene, Phil Vassar

There's more, but I can't think of any now. Again, don't be a jerk. If you don't like any of these songs, suck it up and answer me nicely. It's called manners, ever heard of them?

 I completely agree with  your choices! Especially, Simple Minds "Don't You Forget About Me". That is classic. i would also think that Kenny Chesney's Don't Blink would be a good one. Here are some others I think would work.

R. Kelly: The World's Greatest

Seals and Croft: We May Never Pass This Way Again

Barabara Streisand: The Way We Were

Vitamin C.: Graduation (Friends Forever)

Kenny Chesney: Don't Blink

Brad Paisley: Letter To Me

Baz Luman: Sunscreen

These are just some ideas. I am also a senior in high school and looking for that perfect song! I hope i helped you some!
