I recently wrote for this column about problems with iCloud not matching the correct versions of songs. This is a huge source of frustration for music lovers who want their music in the cloud. But iCloud Music Library has other annoyances. One of these is the iCloud Status that you may see in your iTunes library: No Longer Available.

Record labels and artists are free to choose whether to allow their music to be available on streaming services. There are still some holdouts: Garth Brooks, Bob Seger, King Crimson, the Traveling Wilburys, Pete Townshend, and others are totally averse to streaming. And some artists only stream their music on certain services, as exclusives. This includes Taylor Swifts’ 1989, Adele’s 25, Kanye West’s The Life of Pablo, most of Prince’s music, and much more.

But things get complicated when music that you have added to your iCloud Music Library from Apple Music is pulled. Labels can withdraw the right to stream certain songs and albums at any time, but you won’t be notified. You may see albums and songs in your library, but their titles are a slightly lighter color (depending on the view), and their iCloud status is No Longer Available.
