The Time Of Our Lives

This pop-rock ode to not worrying about the future and having a good time was written by Kesha. The "TiK ToK" singer told MTV News that for this song, she took her formula for writing party songs and applied it to Miley's tween audience. Said Kesha: "Writing for Miley was fun 'cause I think she's funny. I met her and I liked her vibe, so I was like, 'OK, I'll write, like, a party song for a younger crowd.' And that was fun just because I like her."

When Kesha was a struggling musician trying to make ends meet, she earned some bucks penning tunes for other artists, including "This Love" for The Veronicas. However, the paychecks for her creative efforts were often tiny amounts. She told Seventeen magazine, "It was like $1.63 cents for a song I wrote - I think for Miley Cyrus. It was an embarrassingly tiny amount. But I never cashed it and it's on a bulletin board in my house."
