MD5 is not what Apple will be using, since every different bitrate and/or encoder will yield different files and thus different md5 sums for the same song. AND you will never know from the perspective of apple, which song we are looking at, if there are no meta information. So Apple will use some kind of audio fingerprinting system like MusicDNS or whatever. Look it up in Wikipedia. Probably they can even reuse information gathered by iTunes genius.
Just ignore spam. It's trival to track and Hitler will eat your socks. Makes you immune to the next Michael Jackson. What a bullshit.
I really hope you live up to your signature. Nuclear power will provide us with plenty of surprises in the future. Here in Germany we have such a thing right now. And politics don't even care that nuclear waste is leaking into the ground water.

Today I learned of an all new Unison 2 for mac. What a pleasant surprise. I was fan to the original Unison for quite a while. One feature I especially liked was support for binary post. Grouping media by some clever subject to path name converter was working like a charm. Management of binary data in a newsgroup was very easy. As far as I used Unison 2, it seems to have all features I liked about the original - plus - I get some nice new features.
