90 Stuck in the head

How do you songs become stuck in your head

Songs that you possibly haven't actually heard in years

Just suddenly popping up in your head and it stuck there all day

You can hear the voice

the background music

It sounds like you were just listening to it yesterday

Half the time it's one line repeating over and over again

Or on the occasion it's a whole verse

Many times we don't even know where the song is from

Did I listen to it on the radio

Was my sister listening to it on Spotify

Is it from a movie

Because at this rate I definitely don't know
