There's always loads of new talent around at the start of a new year, all hoping to become the next big thing.
Newsround's Clare Youell looks at some of the names you could become VERY familiar with in 2006.
Former Busted star Matt Willis, 22, will be the last of the old trio to launch a new career this year. He's spent the last year in a recording studio making his first solo album.
His first single is called Hey Kid and his new style's supposed to be grunge/rock. (And he's got a cool new look).

This is the Sheffield-based band who knocked the Sugababes off the number one spot with their debut track I Bet You Look Good on the Dancefloor. And that was after building up a fan base almost entirely on the internet.
Their follow-up single, When The Sun Goes Down, is out on 16 January. And their debut album, Whatever People Say I Am, That's What I'm Not, is out on 23 January.
They're three American girls who've formed their own rock band. The girls are called Z Berg,19, Charlotte Froom, 19, and Tennessee Thomas, 21.
Their dads are all bigwigs in the music biz (Charlotte's dad has worked with Sheryl Crow and Paul McCartney.) Their debut album comes out in March.
Everyone knows who he is already but early signs are extremely good for the X Factor winner.
He got the Christmas number one AND his track was the second best-selling single of the year (behind Crazy Frog!)
He'll have a follow-up single and album out soon.
And he's been dubbed the next Will Young.
These are four young lads who are into punk rock. The band's made up of American lead singer Mikey Koltes, bassist Gary "Kill" Kilminster, drummer Johnny South and guitarist Millsy.
They've spent the last year recording their debut album, Somebody Someday, which is out in March. Their single, of the same name, is due out on 20 February 2006. Oh, and they're pretty cute too!
You might not have heard his name yet but this man is the star of THE blockbuster of the year - Superman Returns. He's had a few small TV and film roles but will be catapulted into mega-stardom after this film, which is out in the UK on 14 July.
Interestingly, he went to a fancy dress party as Superman in 2003, and landed one of the biggest movie roles around as the superhero just a few months later.
The lucky young lady who is picked to play loopy Luna in the fifth Harry Potter movie is sure to make waves this year. The film isn't actually out till summer 2007 but there'll be loads of interest in whoever gets the part, from Potter fans and the media . Watch this space!
Already a transfer target for Premiership giants Chelsea and Arsenal, winger Theo Walcott has been making headlines since breaking into the Southampton first team this season, even though he is only 16 years old.
He's netted four times since the season started, including an outrageous winning strike against Luton when he hooked the ball into the goal from the left-hand touch line.
Sprinter Harry Aikines-Aryeetey has already achieved a great deal in his short athletics career, including being named BBC Young Sports Personality for 2005.
That award came just months after a record-breaking performance at the World Junior Athletics Championships - then aged 16 - where he became the first person to win the 100m and 200m in the history of the event.
You might be aware of him from The Christmas Invasion episode of Doctor Who, and of course, as barking mad Barty Crouch Jr in the Goblet of Fire, But this man is going to be huge this year!
Doctor Who is already one of the BBC's most popular programmes, and David Tennant will be on our screens every week from April as the 10th Time Lord. His performance on Christmas Day suggests he's going to be a quirky but loveable Doctor, and a HUGE heart-throb.
Series two of the mystery drama will be on our screens in 2006. As well as the old favourites there'll be some new faces for us to get to know.
The show is up for loads of awards this year too, so the actors are set to be even bigger stars in 2006 than they were last year.
