K so you get lyrics of a song (Say what song they're from) and you post. Then another person posts a lyric from another different song that is related / somehow associated - perhaps with love / the words in the lyrics combined makes a suitable scenario etc.
Do not post an entire chorus / song ...
If you want to sing these lyrics in your head you must sing them to the tune of the old Mario games.
Maybe it could also lead onto a story ?
I start
It's close to midnight
Song: 'Thriller' by Michael Jackson
