Tremor, the integerized decoder for Ogg Vorbis, has been relicensed to a BSD-style license. This means that it is now free to use in portable players, like the Empeg, with no royalties. Here is a page that announces this and has addresses for people to bug the companies

If you haven't had a chance to check out Vorbis yet, head over to the 1.0 demo page at http://www.xiph.org/ogg/vorbis/listen.html

Winamp 2.80 or newer will play .ogg files natively.
