General problems with lyrics, syncing and iTunes (Match)

UPDATE (iOS 8 / iTunes 12):
Today I purchased some songs on the iPhone and later added the lyrics in iTunes - but the lyrics did not show up on the iPhone after syncing back to it -- this is the known problem.
But then I simply deleted the songs on the iPhone and then synced again from iTunes - after the second sync the lyrics were on the iPhone. Maybe this is the way to solve this problem.

With iCloud, iTunes Match and downloads directly to the iPhone it really get's complicated. You are no longer master of your own songs. When you add lyrics in iTunes on the mac and sync back to the iPhone, the lyrics don't show up! In other cases the old lyrics before the change show up!?

It is a problem with iOS 5. All this iCloud and Match stuff is even confusing Apple, it seems.

Deleting the song on the iPhone and then sync it back from the computer does not help.
What you have to do:

1. Copy the song from iTunes to your desktop (or any other folder) -- the lyrics are contained within this file
2. Delete the song in iTunes (with "move to trash")
3. Delete the song on the device (in the built-in music app, with a swipe gesture)
4. Sync from computer to device by cable
5. Add the song back to iTunes
6. Sync again

--- Now the song will display the lyrics both in the music app and in SmartPlaylist (in SmartPlaylist you must empty the cache with the new ⌘-command "Empty cache after sync" or do a complete restart)

Like that you will loose the Rating, Play Count and Skip Count and get a new Date Added. It is a pain.

Maybe it's better to download songs from Amazon, after all. Then you don't have those troubles.
