windows and linux users are really missing out
Editing metadata in amarok involves double-clicking on the field you want to edit, typing something, and pressing enter. I find it hard to believe that fishbowl would have a problem doing this (considering his UID, I expect it could be beard-related interference), and even if he doesn't fill out tags manually it will guess tags from the filename so it's not like there's a huge list of completely unnamed files to dig through. There is also a traditional metadata dialog with more options. You can select multiple files and assign shared information (album, genre, year, etc.) to all of them at once, assign track numbers sequentially, and similar things I've come to expect from other applications and been sorely disappointed not to find.
As for spotlight, honestly I can't say I've ever felt a need for that kind of functionality. If I'm looking for a song, then I open amarok, which is actually tailored for searching music. In fact, linux has tools similar to spotlight, one being "Beagle" which comes with my distro, but I always uninstall it because it drives up my system load. That's an implementation-specific problem but I personally don't ever feel the need to search my entire system for something when there is a domain-specific application that I know already has information about it.
Many people are unenthusiastic about their work.
