If there's lessons

[Allthewayanime]

Could someone explain why in the first line of the song is used 'is' instead of 'are'?

If There’s Lessons To Be Learned,
I’d Rather Get My Jamming Words In First Oh
Tell Ya Something That I’ve Found,
That The World's A Better Place When It’s Upside Down Boy

[Beeesneees]

Songs often don't follow correct rules of grammar.
Grammar is pushed aside for rhythm/rhyme/poetry.

It's not the only incorrect grammar in that quotation.
