OOF NOBODY GOT IT.

However AnaWritesRandom DID get the artist so I'll give her that.

The song was "Rolling in the Deep" by Adele!

I'll try to get back to easier ones-

Difficulty: Medium

Oh, captain, let's make a deal

Where we both say the things that we both really feel

I feel scared and I'm starting to sink

And I only sink deeper the deeper I think

Oh, captain, oh, captain, deal

Oh, captain, deal, oh, captain, deal, oh

May the odds be ever in your favor
