Being either a music person or not, if you know the lyrics and instrumentation to a song it is incredibly hard to try to sing and catch up with everything:
While singing along to Taylor Swift songs
Me: *sings guitar part*
Me: *pretends to drum along*
Me: ‘Cause I seeee sparks fly whenever yooouuuuuu smi-
Me: na na na na na ana na ana
Me: *keeps banging pretend drum set*
