The 25-year-old singer has been revealed as the big winner as the American Society of Composers, Authors and Publishers (ASCAP) reveals this year's honourees, shining a light on "incredible British songwriting and composing talent for their continued US success".

The 'Someone You Loved' hitmaker earned Lewis the prizes for Song of the Year and Top Streaming Song, while 'Before You Go' was a Winning Hot 100 Song, and both tracks were behind his Songwriter of the Year success.

In a special video greeting to all of this year's ASCAP London Music Awards winners, ASCAP Chairman of the Board and President Paul Williams said: "We've learned that however wide the space is between us, we are connected at a soul level.

"Your music reminds us of that. When your music connects with millions of people, that's power.

"That can change the world... Congratulations to all of this year's winners for your achievements."

Also recognised among the top songs of 2020 was Black Eyed Peas and J Balvin's hit 'RITMO' - co-written by Pete Glenister - which features a sample of Corona's 1995 hit 'Rhythm of the Night', and the track received both Top Hot Dance/Electronic Song and Winning Hot 100 Song prizes.
