Portishead star Geoff Barrow has accused R&B singer The Weeknd of sampling the group's 2008 track Machine Gun without permission. Barrow allegedly denied The Weeknd's request to feature a portion of the band's song on his new track, Belong to the World, and he was outraged to learn the 23 year old, real name Abel Tesfaye, deliberately ignored his wishes. The single premiered on Twitter.com on Monday (15Jul13) and in a post to Tesfaye, Barrow writes, "When someone asks to sample you and you refuse they should have the respect as a fellow artist to not use it." Barrow also used the opportunity to deny rumours his decision was based on money, adding, "We usually give sample clearance to tunes we like. its (sic) got f**k all to do with money! As most of them are hiphop artist (sic) that are skint (broke). Feels like I'm being used to promote the track now. I'll shut up."
