Fantanos, I need your help with picking a gradutation song

I have to choose the music for the end of a graduation ceremony. It is gonna be the final song that is played while the students are leaving the hall.

I do not want it to be anything horrible like an Imagine Dragons song but it still has to be somewhat mainstream. I would also like something more modern, so no "We are the Champions". I was thinking about Homecoming by Kanye West but that seemed like a bad idea considering what a moron he is.

Do you have any ideas?
