Well, what you see when using an iPod or iTunes are the tags, so the artist, album, track title, composer, genre, and other useful info are all visible. You don't see, or have to know, the file names, and the filenames can be short because the information needed to search and sort is all in the tags. The tags are read at the time you load the music, the database is populated, and the only lag comes when you have to re-read or load the database (on a computer, that happens when you open iTunes; on aniPod, it happens when you reboot, which is very rare).
So there's a fundamental difference between how a Brennan device works, and how an Apple device works. Tags are more flexible and thus easier to USE; filenames are more straightforward and thus easier to LEARN.
