If you can't locate a music you purchased from the iTunes Store on your device, it may have been erased and you'll need to redownload it from the store. The song will be downloaded to your smartphone when you tap the cloud button next to it. Then enter your redemption code to re-download any songs that were removed.
I recommend that you log out of the iTunes Store, shut iTunes, wait a few seconds, then reopen it and log back into the iTunes Store. After that, look for the track in your purchase history and see whether it's hidden. At this time, you should be able to re-download it.
If you look at the File tab of the song's Info panel. If the song is not in a protected format, the issue may be that it is only on iCloud and has not been downloaded to the Mac. Make sure you have a local copy of the music by downloading and playing it in iTunes. Then try again.
On an iPhone, iPad, iPod touch, or Android device.
If you already have a music in your iTunes library, you will not be able to re-download it until you delete it. The song is nowhere to be found in my library, purchased playlist, buy history, or even hidden music. It has nothing to do with my account. This is why I attempted to redownload it.
The problem is that it says the file is unavailable when I try to download it. There's no way for me to know if Apple deleted it by mistake or if they are just trying to prevent me from redownloading it. Either way, this means that I can't use iTunes to add more music to my library anymore.
The only way to fix this is to delete the album from my computer. Then, I would need to re-add all of my songs one by one. This could take a very long time depending on how many songs there are on the album.
In conclusion, redownloading music from iTunes is not possible unless you delete the original copy first. This issue came up because I tried to redownload an album that wasn't bought from the iTunes Store. If this had been store-bought content, then it would be possible to re-download it later.
Music may be purchased via the iTunes Store.
If you are unable to play a music purchased from the iTunes Store, you may have surpassed the number of machines on which your purchases may be played. See the Apple Support article for further information. If you try to play purchases in iTunes for Windows and are prompted to approve your machine, do so.
