Xbox Music app playlists are missing songs when viewed on a Windows Phone 8

You create and add a playlist in the Xbox Music app on Windows 8 with your Xbox LIVE account. But when you view the playlist on your Windows Phone 8, not every song in the playlist is listed.

This issue happens because Windows Phone 8 only shows songs on a playlist if the songs are currently in your cloud collection. To resolve this issue, add the missing songs on playlist to your cloud collection:

1. Sign in to the Xbox Music app on a Window 8-based device.
   
2. Locate the song in the Music Store:
• Use the Add to my music button to download and it add to your cloud collection.
  
• Open the playlist in the My Music area, and then select Download to add the song to your cloud collection.
3. Repeat step 2 for each missing song.
   
4. Sync your Microsoft account on the Windows Phone 8 phone:
• Tap Settings, tap Email and Account, tap and hold on your Microsoft account, and then choose Sync.
