Remember last year when Portishead's Geoff Barrow accused Abel Tesfaye (The Weeknd) of sampling 'Machine Gun' without permission? Well, it seems the feud is far from over.

Earlier today Barrow took the issue to Twitter by posting a photo of a letter he received from The Weeknd's management last year asking for his permission to sample 'Machine Gun' for what would become 'You Belong to the World': "When someone asks to sample you and you refuse they should have the respect as a fellow artist to not use it."

Although Tesfaye apparently claimed that his track didn't use a sample, Barrow seems to suggest he recorded a similar beat after being refused permission. Check out the letter below.

Listen to both tracks below:
