[Nicolai P. Zwar]

Yes, proper tagging is indeed very important.

But sometimes, tags get mismatched.

It seems, the two John Williams’ are generally separated, but sometimes, they get mixed up.

And sometimes one John Williams performs music composed by the other John Williams. 🙂

As I said, what kind of tagging system does the job for you may depend on your needs. Many people with a few hundred pop songs on their MP3 player may do just fine with TITLE and ARTIST, it’s all they need. Some people don’t even need ALBUM. But you can’t manage a larger music collection like that, especially not a larger classical music collection.
