This infinite thread about mp3lame should remind us one thing: using mp3 is lame, even more for content creators... At this point in the history of streaming audio, we whould stop using proprietary formats and use free formats like ogg. The mp3lame library cannot be distributed with free operating systems, and that's one of the reason why it's difficult to use.
