What Do I Know? – Ed Sheeran ringtone

Download What Do I Know? ringtone:

We could change this whole world with a piano
Add a bass, some guitar, grab a beat
And away we go
I'm just a boy with a one-man show
No university, no degree
But lord knows everybody's talking 'bout exponential growth
And the star monkey crashing in their portfolios
While I'll be sitting here with a song I wrote
Sing, love could change the world in a moment
But what do I know?
