Vorspulen literally means "to fast forward", like on a tape or video player. It's an interesting and somewhat modern word to find in a song, making it memorable.
In the context of "Bye Bye", Sarah Connor uses it to express a strong desire to skip past the current difficult times (likely referring to the pandemic and its restrictions) and get straight to a better future where everyone can be together again. It captures a universal feeling of wanting to accelerate through hardship.
"Bye Bye" is Sarah Connor's ode to the end of pandemic restrictions. She sings about being bored at home with nothing to do, missing her friends, and dreaming of the moment someone wakes her up to say it's finally over.
The chorus imagines throwing one huge party once that day comes: everyone standing close together again, old and young, nobody left alone at home. Verses picture other ways people tried to fill the empty time, like milking goats or pressing olive oil, small hobbies that could not replace real closeness.
By the bridge she names it directly: she is done with distancing and just wants to go back to normal life, share a glass with someone, and hug her friends without worrying. It is a hopeful, upbeat song written for a very specific moment, but its wish for connection still lands as a simple, universal one.
