I am looking for a Finnish song!

So I was working out on my local Fit1Club and heard this tune (must be honest, wasn't the first time I heard it, but the first time I actually realised I liked it and tried to listen to the lyrics)... So long story short, I didn't get any of the lyrics but "sun nimi kirjoihin" or it could be "sun nimi kirjoitin". This comes to the end of the chorus, and it might be followed by some WOOHs and preceded by a word that ended in -VA. The tune is a poppy one, maybe rock pop if you rather, the vocalist is female and I can attest that is not Jenni Vartiainen, Sanni, Haloo Helsinki, Vesala, Maija Viikuuma, Kaija Koo, Leoonora, Aurora, Suvi Teräsniska, Jaana, Chisu, Anna Abreu, Erin, Saara or Joona Tervomaa (although is kind of similar music, maybe younger?).

Any wild guesses?

EDIT: I can now also say it was not Mariska (with/without Paha Sudet), Laura Närhi or Iisa
