Hatta's Journal: Usable?

iTunes is one of OS X's "killer apps" And one would think it would "just work." Not so. One of the most trivial things to expect from an audio player is that when you load a playlist it will play those files, and only those files, in order. However when I download an m3u, itunes opens up and it puts the contents into the "Library" with every other music file I've ever played. What's more, is that it intercalates the songs in the playlist amongst the other files with no regard for the order in the .m3u. In order to play a .m3u playlist in order I must download the m3u, create a new playlist, then drag the m3u onto itunes. And then I STILL have to click the bar on top to get them to sort properly. Does this "just work"? I think not.
