Q: Both the store and my MAC get error message "Can not locate Bonus track"

Hello mysticmel,

It may help to delete the affected content, then redownload it from the iTunes Store.

How to delete content you've downloaded from the iTunes Store, App Store, iBooks Store, or Mac App Store

mysticmel,

The item must be downloaded via your purchase history rather than the store page wherein it appears, as detailed below.

iTunes Store

1. Open iTunes and go to the iTunes Store.
2. Click Purchased in the Quick Links section.

1. Select the content type that you want to download (Music, Movies, TV Shows, Apps, or Books).
2. Select Not in My Library to view purchased content that isn't on your computer.

1. Find the item that you want to download. You can browse using the menu to the left. If you have more than 2,000 songs, you will see Recent Purchases instead of All Songs or Albums.
   
2. Click the Download icon next to the item you want to download.
   If an item is already in your library, the Download icon won't appear.

Download past purchases
