Every year, the BBC News website surveys the UK's most influential and knowledgeable music pundits to uncover the hottest new music acts.
The Sound of 2005 top 10 was published a year ago - but how have the chosen artists fared?
The Sound of 2006 countdown will begin on Monday. One artist from this year's top five will be revealed every day until Friday, when the winner and full top 10 will be announced.
1. The Bravery
Electro-rockers The Bravery produced a well-received debut album, which was a top five hit in the UK and spawned a top 10 single, An Honest Mistake.
They also gained an enthusiastic live following thanks to a constant tour schedule and a string of festivals.
But the public at large was reluctant to board the bandwagon and the New York band failed to stick at the right end of the charts. Singer Sam Endicott also hit the headlines for a spat with The Killers.
2. Bloc Party
The cerebral guitar pounders were big favourites with indie hardliners. Silent Alarm was named the best album of 2005 by the NME and was nominated for the Mercury Music Prize.
They also scored two top 10 singles, with two more reaching the top 20.
Rapper Kano rose to the top of the British hip-hop scene, but failed to make a mainstream breakthrough. He received the title of best UK newcomer at the Mobo Awards.
4. The Game
Helped by his mentor 50 Cent, US rapper The Game had a huge album and a string of hit singles - even if subsequent publicity surrounded the pair's feud and alleged links to shootings.
5. Kaiser Chiefs
This Leeds indie-pop bunch were one of the bands of the year. Their infectious odes to English life captured the public's imagination and their showmanship wowed live crowds.
They were the only UK band to appear at the US leg of Live 8, scored three UK top 10 hits and got a Mercury nomination.
6. KT Tunstall
Another success story, singer-songwriter KT Tunstall achieved widespread popularity without abandoning her acoustic folk roots.
Her album Eye to the Telescope sold a million in the UK and her song Black Horse and the Cherry Tree won the best track prize at the Q Awards.
7. The Dead 60s
Scouse ska revivalists The Dead 60s got a warm if not wild reception, registering three singles in the lower reaches of the UK top 30 during the last 12 months.
8. The Dears
Canadian stalwarts The Dears generated considerable excitement with their melodramatic indie anthem Lost in the Plot a year ago.
But despite that promise, they faded from view as their countrymen The Arcade Fire went on to take more plaudits.
9. Tom Vek
Still buzzing along nicely, this offbeat electro-pop songwriter won many fans if not a mainstream audience. He is still an underground hero and has started to create ripples in the US.
10. The Magic Numbers
Heartwarming, harmonic melodies and sunny personalities made them one of the UK's best-loved breakthrough bands.
Their Mercury-nominated album was perfect summer soundtrack material - even if they got more column inches for storming off Top of the Pops.
The ones that got away
James Blunt had the UK's best-selling album of 2005 and opened the door for fellow songsmiths Daniel Powter and Jack Johnson.
The Arctic Monkeys and Pussycat Dolls also made major breakthroughs in the last 12 months but were not on the Sound of 2005 radar.
Keane won the Sound of 2004 poll before going on to become one of that year's biggest bands. The top 10 also featured future stars Franz Ferdinand, Razorlight, Joss Stone, McFly and the Scissor Sisters.
The inaugural survey, Sound of 2003, was topped by US rapper 50 Cent before he hit the big time. Dizzee Rascal, Audio Bullys, Mario and Sean Paul were among the others on the list.
