Musical puns

I was driving down pitch perfect lane when my car got a flat. I realized when I got out to take a look it was because I had driven over a bunch of sharp keys. So I called for road side assistance and while I waited, I listened to music, turned up the bass and read my notes from class. 

My tire was fixed in no time, and I figured a flat is better than getting stuck-ado in the mud. And I stayed calm and tried not to get all jazzed up.
