Music Banter - Need help picking a song!

Hi, My name is Mel and i'm planning my senior retreat for my school.

Our theme is Seasons of Change ( relating to friendships and how you changed over the past 4 years)

I can't seem to find a good song besides Graudation friends forever Vitamin C And well EVERYBODY uses that and i wanted to be different

Can you guys please give me some songs that would be good?

WE were going to use Seasons of Love from Rent but half my class hates it
And also Times from BSB but EVERYBODY from our class hates BSB

SO could you help me out??
