Alvaro Estrella with "Baila baila" beat the hard rockers in Little Sister in the first duel.
During Friday's genre rehearsal, Alvaro Estrella had problems with the wall in the background.
But now it worked as it should and Little Sister had to take her pyrotechnics and go home.
Paul Rey reached the final for the second year in a row when he beat Frida Green in the all-Scanian second duel.
He did so despite the stomach ache that caused him to miss Thursday's genre rehearsal during the week.
Now he gets to sing on to the song "The missing piece", which is about the love of his newborn daughter, another week.
Star shot Clara Klingenström managed to stop the veterans Eva Rydberg and Ewa Roos with her "Do not need you today".
The song is one of the most personal in the entire Melodifestivalen starting field this year and apparently it managed to capture TV viewers.
Klingenström has previously told about how she herself wrote the lyrics at the piano to get out of a difficult period in life.
In the last duel, which was also the youngest of the year, Klara Hammarström and "Beat of broken hearts" moved on.
Last year, she finished in fifth place in her competition.
But this year she managed to get to the Second Chance and beat Efraim Leo's boy band pop.
