Ogg is good open source alternative to MP3. Lot of the media rippers on Linux
will default to Ogg. However, if you DJ and need to burn tracks on a CD, and
spin the CD on a house system. You as you know going to require a MP3 format. If
you use your Lap Top to DJ with you can use Ogg with no problem. Ogg is a very
hard sell to makers of multi media devices. Yet, it is growing. Why pay money
for some thing when you can get it for free. I support open source, but when
your multi media player only supports MP3 and WMA. There is little choice.
