The British musician claims he had denied The Weeknd's request to feature parts of the group's 2008 release on Belong to the World, but it seemed the Canadian star had ignored his wishes when he debuted his latest tune on the Internet on Monday (15Jul13).
Taking to Twitter.com, Barrow ranted, "When someone asks to sample you and you refuse they should have the respect as a fellow artist to not use it."
The Weeknd, real name Abel Tesfaye, has yet to speak out about the song complaint, but it appears he has been in touch with Barrow to dispute the copyright allegations.
Returning to his Twitter page on Wednesday (17Jul13), Barrow writes, "Seems The Weeknd have (sic) said there is no sample used or enough likeness to MAChine Gun to warrant any infringement....or credit."
Ironically, The Weeknd recently admitted he had drawn on Portishead's work for Belong to the World and the rest of his upcoming album, Kiss Land, telling Complex magazine, "I wrote a letter to the producers of Portishead and let them know this album is inspired by them."
