Je ne te connais pas

(literally translated)

I do not know you yeah yeah yeah! I not myself in remembers yeah yeah yeah!
Are for you on that this is me yeah yeah yeah!
You do not be mistaken yeah yeah yeah!

that always begins similar one kisses oneself one drinks a glass that always finishes similar one is said that one remembers.

awesome song from the Outlander commercial. I'd imagine it's about someone who the writer of the song was dating and broke up over something that made that person realize they didn't know who they really were.

I'm going to translate with a little, er, more nuance than an automatic translator.

je ne te connais pas - i do not know you yeah yeah yeah ! - yeah, yeah, yeah! je ne m'en souviens pas - I don't remember, yeah yeah yeah ! - yeah, yeah, yeah t'es sûr que c'est moi - you're sure that it's me yeah yeah yeah ! - yeah, yeah, yeah est ce que tu ne te trompes pas - are you not mistaken? yeah yeah yeah !

ça commence - it begins toujours pareil - always the same on s'embrasse - we kiss/embrace on boit un verre - we drink a glass ça finit - it ends toujours pareil - always the same on se dit qu'on se rappelle - we tell each other that we'll call back

They're using "on" informally as we, not "one" in this song. It makes much more sense this way. It's rather straight forward, she meets a guy at a bar, and it seems that they are in a cycle of getting drunk and forgetting who the other is.

i made a mistake in the last comment:

on se dit qu'on se rappelle - we tell each other that we'll remember*

This song is pretty much about the singer at some club/bar and some guy is hitting on her. She's saying she doesn't really know him but, but she's a bit drunk, so anything might happen.
