Newcomer Kanye West leads the field for this year's Music of Black Origin (Mobo) Awards, with seven nominations.
Kanye West is a successful producer in the US
The singer and producer is up for best video, best collaboration, twice, best single, best album and best producer, as well as best hip-hop act.
Other nominees include Jamelia - with three nominations - Jamie Cullum, Dizzee Rascal, Lemar, The Streets, Joss Stone, Gemma Fox and Amy Winehouse.
The awards ceremony will be held at the Royal Albert Hall on 30 September.
The Mobo awards, now in their ninth year, have grown into the largest urban awards show in Europe.
However they also provoke controversy, and in 2003 gay group OutRage! led a protest against Mobo Award nominees Beenie Man, Elephant Man and Bounty Killer, who use allegedly homophobic lyrics.
OutRage! called for several reggae artists be banned from the 2004 shortlist before the nominations were revealed, including Vybz Kartel and Elephant Man, who are both up for awards.
Their spokesman said the Mobos were "colluding" with both artists, giving them "credibility and legitimacy".
Jamelia has been nominated for three awards
In 2003, Rap star 50 Cent swept the board at the awards, winning three prizes.
This year, Mobo have added two new awards to the show - the best collaboration award and best ringtone award.
Kanye West, who is one of the top US producers working with Alicia Keys and Jay Z among others, released his first solo album, The College Dropout, earlier this year.
R&B singer Jamelia has been nominated for best single, for Thank You, best video and UK act of the year.
She will also face the likes of Amy Winehouse, Dizzee Rascal, Lemar, The Streets and Joss Stone for UK Act of the Year.
Jamelia said: "I'm totally over the moon. It's absolutely overwhelming to receive so many nominations."
Teenager Joss Stone has also been nominated in the best album category for The Soul Sessions.
Other UK acts nominated include artist/producer Wiley - nominated for best UK newcomer and best producer.
He said: "I'm overwhelmed, and I hope to be nominated for more awards in years to come in all categories.
"I've watched the Mobos for years and I always knew I'd get there one day. It's a great feeling."
The first Dutch Mobo Awards are to be held in the Netherlands on 2 October.
