How to sync back Lyrics of music to iTunes?

My setups: - I use iSyncr for PC to sync my Android devices with iTunes. - I use PlayerPro Music Player which hooks with iSyncr's system. Ratings and Play Counts are synced with iTunes both ways, but that's not true for Lyrics of music. If I add Lyrics in iTunes (Right Click ~> Get Info ~> Lyrics (tab)), I can see it in PlayerPro on Android. But, when I download lyrics using PlayerPro (Long Tap ~> View Lyrics), I fail to find it in iTunes after sync. I have searched filesystems of Android devices to find any file, database containing Lyrics, but it seems that PlayerPro saves it in ID3 tag of music files. So, I don't see where's the problem. I have got the feeling that iSyncr doesn't sync back for such things, but I am not sure. How to sync Lyrics from Android to iTunes on PC? I can use alternatives for lyrics sync & lyrics download as long as I can view lyrics in PlayerPro & other syncs work as before. **Update:** PlayerPro support has confirmed that lyrics is saved inside music file. In case something goes wrong, it is saved in .lyr file in the directory of music.
