Tips, Tricks and Tools To Help You Sing!

what songs are good songs to sing in a graduation?

I need songs that inspires us to move on and take a step forward. Some songs are "One Step At A Time by Jordin Spark" and another is obviously graduation/friends forever by vitamin C. I need the lyrics to mean like:

1. It's a new beginning
2. We don't need to rush things.
3. A time to be remembered

ALSO, i don't want the song to be sad. I want it to be mostly rnb or pop
