[Advocate Play Ogg] Ogg Playing

[advocate]

Hello, friends... I have some questions... (I'm not sure this is the 
place to ask this, but, anyway... I'm sorry if it isn't)

Can a band be sued for giving their songs for free in MP3/WMA format? Or 
only the software that plays MP3 has restrictions?

I'd like to make a sort of online radio in ogg... I have a small 
personal website, only for hobby, and would like to upload my favorite 
songs, and play them randomly... like m3u, pls... I'm not sure how to do 
that... and I was hoping to have javascript to automatically play it, 
stop, go to next song, etc... maybe it's asking too much... Does anybody 
know if this is possible? Where can I learn how to do that, if so?

Do you think open-source enthusiasts should offer proprietary options 
too, after all, free software is about freedom, or only the free ones?

Thank you so much
