I heard the lyrical song from Harry Styles.

Generally we don't specify a song has lyrics - in fact it's usually the opposite, in English you'd specifically say instrumental song if it didn't have vocals, but having vocals is assumed to be the default.

I liked the guitar, but it was a bit hard to understand wordthe words/vocals.

Words in a song are often referred to as vocals, though it's also ok to say "the words"

So now I hear of repeatlisten repeatedly to two and a half minutes of that to write songthe words of the song.

You could also say "I listen to two and a half minutes on repeat", but "on repeat" is pretty much only used for songs, while repeatedly can be used for anything.

The song is about a girl whicho doesn't felllike (?) herself being accepted in a home.

Not quite sure what you meant by "fell herself", so I'm guessing you wanted "like"?

If you are interestinged, I givecan show you a site.

"interesting" = causing interest
"interested" = expressing interest
