I understand the assumption, but I don't like it
...
The assumption reminds me of the way WMP or iTunes works things. Since the rest of Media Center is AMAZINGLY configurable it's frustrating that something like this is not. I have a ton of songs that I've gathered from all corners of the earth over the last 10 years that have only Artist, Track Name, and Genre filled in since I've never had the luxury of a look-up feature such as this. I've been working at manually filling in all the tags, but it was a loooooooong process in iTunes. So it would be great to have an "update missing" or "update what I want" option.
Personally (and for others I would guess) I only want to update FACTS from a database anyway (ie: Artist, Album, Track, Track#, Year, etc) while leaving subjective fields alone (ie: Genre, Mood, Situation, Tempo). So a simple checkbox list under the main menu would be an awesome feature.
Obviously I don't know how the database lookup is setup, but based on the way the rest of the program seems to work it doesn't seem to difficult to have some sort of "ID3 field mask" implemented...or my assumption could be completely wrong, it happens...
So far in my newbie analysis of the program this is the only real issue I've come across so far (feature wise anyway). So I do want to point out that otherwise, I'm quickly getting hooked on Media Center. Thanks!
