Hello there, La Clairiere Feerique.

I understand you are having issues with playback of a purchased song. If iTunes in the Cloud is available in your country, it might be best to delete the song from your computer, then re-download from your purchase history.

To delete a song the following Knowledge Base article offers how to delete from your iOS device:

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

Music

Open the section below for the device you are using.

iPhone, iPad, or iPod touch

Mac or PC

Before you delete, find out if you'll be able to download the song you deleted again (it depends on where you live). To delete a song:

1. Launch iTunes.
2. From the Library pop-up menu, choose Music.
3. Click Songs in the navigation bar.
4. Click the song you want to delete.
5. Press the Delete key on your keyboard.

In iTunes 11, the album cover art will remain visible, but a cloud icon will appear on it to allow you to download the item again (in countries that support this).

Note: If you didn't purchase a song from the iTunes Store, you won't be able to download it again for free from iTunes in the Cloud. You might want to back it up somewhere on your computer.

Afterwards, re-download the purchases from your purchase history:
