I have 1300 duplicate songs on my imac. No dupes on my iphone5
I have about 1300 songs and somehow they are all in my iMac iTunes twice. Whole lotta work to delete 1300 tunes manually. I'm looking for a short cut. I noticed there are no dupes on my iPhone 5. Would deleting all the tunes on my iMac and then resyncing be the easiest thing to do??
iMac (Retina 4K, 21.5-inch, Late 2015)
