Sounds weird to me

"Kenapa Singgah Kalau Tak Masuk"

Okay, this is one of the weirdest songs that I've ever listened to.
I dunno about you readers, but I simply dun like the song title.

And there's one part of the lyric that goes "Semenjak dua menjak"... Gramatically, it is soooo wrong, man!
While the song goes to the chorus part... it sounds like lagu raya... I mean, is it just me... what do you think? Hmmmm.....
