The 28 songs will be fighting it out in February and March next year for the right to represent Sweden in Vienna. Five prime-time TV shows will lead up to the grand final, televised live from Stockholm's huge Friends Arena. Who will follow in Sanna Nielsen's footsteps and represent Sweden in the Eurovision?
Many of the names will ring familiar to followers of the contest, with people like Jessica Andersson, Andreas Johnson and Magnus Carlsson competing for the 456th time. Well, almost. But there are some new names, while some of them are completely unknown, others do have their followers, like the duo Samir and Viktor. Samir is best known for being in the scandalous docu-soap Paradise Hotel, and has almost 300,000 followers on Instagram alone. They had a big hit this summer with the song "Success".
Other throwing their hat into the ring for next year are a Swedish band fresh from the Australian version of X Factor, called JTR, where they finished in seventh place.
"Every Swede has some kind of relationship to Melodifestivalen", they told Radio Sweden, "We all grew up with it. We wanted a positive, uplifting pop-song, and that's what it is. It's poppy, building it up. I think everyone wants to win, but there's a lot of good competition, so who knows?
Another singer who got her big breakthrough this year is Kristin Amparo. She too is a veteran of talent shows, competing in the Swedish version of X-Factor, but is probably best known as the vocalist on the huge summer hit "Din Soldat" together with rapper Albin. Her recent success led to some in the music industry warning her off competing in Melodifestivalen, worried it may damage her career, but competing in the show has been a dream for her, she says.
"It's been with me all my life", she says, "I grew up with it. I love those kinds of traditional things. Even though it has changed in many ways, the song is still the main focus. I like that. And I also like plenty of the old songs from before. In Swedish you say they are like "pearls". I want to say to my grandchildren one day that I did it, and that I'm proud of it."
Kristin Amparo has written her song herself, together with veteran Fredrik Kempe and David Kreuger. She describes it as "a warm intimate song" with only piano and strings.
But while she is one of the newcomers to the contest, other names will be more familiar to Eurovision aficionados. Marie Bergman, Ellen Benediktsson, Caroline Wennergren, Linus Svenning and Behrang Miri are even more familiar names that will all try their luck again.
But even though the general public and the media still have yet to hear the songs, two favourites have already emerged.
Eric Saade, who won with Popular in 2011 is back, and with his sights firmly set on winning Eurovision in May. His biggest challenger to the crown may well be pop singer and TV host Måns Zelmerlöw, who last competed in Melodifestivalen in 2009 and has since hosted the show. He says he is in the contest to win it.
"It's an amazing song", he says, "it's very big, very epic in a way, and there are a lot of elements that you could use on stage with effects and so on. I wouldn't participate if I didn't think that this song had a shot at winning. But as long as I have a good run and I do my best... that's quite boring but it's the truth."
The contest will also see the first ever entry in the Sami language. Jon Henrik Fjällgren will sing the song "Jag är fri (Manne Leam Frijje)".
