Sync song metadata into id3 tags?
I've noticed that for some of the songs I have iTunes kept metadata about the song (artist, album, etc) in its own internal database, instead of storing it in id3 tags. This worked OK if songs are played back only in iTunes and on iPod. However, my wife got recently Android phone, and all these songs show up as 'unknown artist/album' on it. Is there a simple way to have iTunes sync the information from its internal database back into MP3 files (and to keep preferring to store that info in the files, and not in its internal database)?
Related question is, for even more songs, iTunes elected to store album artwork in its internal database, instead of in the MP3/AAC files themself. While iTunes syncs artwork to iPods, this obviously does not work for any other type of device. Is there a way to have iTunes store artwork in the files only, and not use its internal database for that either?
