Apple iTunes11 allows you to view music that isn’t on your computer but own via the iTunes Store. This feature can litter your music list with tons of music tracks you don’t want showing in your list. Fortunately, you can hide iCloud Music in iTunes 11 with these steps.
Music files that aren’t downloaded but available from iCloud have a cloud icon visible next to them if the iCloud Download column is visible.
2. Select View > Hide Music in the Cloud.
Now all those annoying songs you wish you never bough will be removed from iTunes.
