Music by artists such as Adele and Nirvana were removed from YouTube over the last few days. The removals were due to a copyright agreement that was due to expire; it's now been renewed and the music is returning.
Over the weekend, videos by some of music's biggest stars started disappearing from YouTube. Artists ranging from Adele to Bob Dylan, Green Day and Nirvana were all removed. In some cases the disappearances were really dramatic, so for example almost every video was removed from the official Nirvana channel overnight. The good news is that they're coming back.
