Hozier, Arctic Monkeys and George Ezra are among the nominations for this year's Ivor Novella Awards.
The range of musical influences in the categories has been hailed by prize organisers, with 70% of nominees recognised for the first time.
Hozier's Nina Cried Power is up against Arctic Monkeys' Four Out Of Five, composed by frontman Alex Turner, and Ben Howard's Nica Libres At Dusk. The winners will be announced at a star-studded event at Grosvenor House in London on May 23.
Works eligible for the awards have to have been commercially released in the UK in 2018 and have a British or Irish songwriting or composing contribution of at least a third.
Crispin Hunt, chairman of The Ivors Academy, said: "The works nominated for The Ivors 2019 are brilliantly diverse, and we're delighted to see so many first-time nominees recognised.
"As the only peer-nominated music awards in the country, they are a fantastic reflection of the exciting emerging talent of British and Irish music creators today. Our congratulations to all nominated."
Ezra is among the nominations for most-performed work for his song Shotgun, which is competing with Breathe by Jax Jones and Ina Wroldsen.
Jorja Smith's Blue Lights, written by Guy Bonnet, Dizzee Rascal, Roland Romanelli and Smith herself, has been nominated in the category of best contemporary song.
Young Fathers' Cocoa Sugar has been nominated as one of the best albums of 2019.
