Last week, when songwriting titles and credits for Kendrick Lamar's new album were unearthed, there were four surprising names on the list - most notably, Messrs. Hewson, Evans, Clayton and Mullen.

Most people - including us, it must be said - assumed that the LA rapper was sampling one of U2's songs on the record, but it appears that Bono and co. are genuinely featuring as guests on the album.

The follow-up to 'To Pimp a Butterfly' is called 'Damn' and is released this Friday, and the song featuring the Irish band is called 'Xxx'.

Rihanna is the only other credited guest on the record, so they're in good company.

The question is, will it be any good? We'll find out on Friday.
