I want to convert a large number of mp3s

I'm not sure if this is possible, much less how to go about it; so I'm going to ask here.

I just installed ubuntu and because of corporate bullshit they don't include any support for playing dvds or mp3s. I managed to get it to work, but it makes me realise that in the future it might not be as easy to deal with mp3s so it might be best to switch to something like ogg which is somewhat guarenteed to be playable for a while.

I have about 8 gigs of mp3 and wma files I'd like to convert over to ogg; is this possible? Is there a way (preferably in linux) to automate it so I don't end up with foo.mp3.ogg (which would happen by running a shell script like" for x in *.[M,m]??; do conversion_program $x $x.ogg;done") ?

Is this too much to ask for?

I wouldn't do that, not that I dislike OGG (in fact I always use it when I can), but you'll lose quality in the conversion (unless you make the files huge, and you'd still lose something and gain artifacts). Better use a good OS with support for all audio formats in a standard way that works with any player.
