"Kärlekens Tunga" - September.
She was the breakthrough artist from last year's "Så mycket bättre" of course, and her success deservedly continued throughout this year. After the massive "Mikrofonkåt" this was her follow-up single - her very own inimitable electro take on the Eldkvarn song.
If you want to hear a completely different version of the song, check out this video clip, from when Petra performed with Salem Al Fakir at his Norrköping orchestra show back in March. ("Kärlekens Tunga" is at 3.55.)
