Seriously, there could be some limitations depending on your view.

1. You're going lossy to lossy so quality will be degraded
2. You *may* lose ID3 tags
3. Depending on how many mp3's you have, it could take a loooong time
Google for mp32ogg and see what you come up with.



     

yes, but that program only does 1 file at a time .. I'm talking about 
batch converting everything. I'd be willing maybe to accept the losses :)
   

OK, here you go. As an added bonus, it keeps ID3 tags. Requires mpg123
to convert to wav, mp3info to read id3 tags, and of course oggenc.

   WOOOOOOOOWWWWWWWWWWWW!!!!!!!!!!!!!!!!!!
awesome ... I owe you big time!!!!! thanks a LOT!!! this is an awesome. 
It also works recursivelly!!! A big surprise was that on my first mp3 I 
got 5.6mb to 2.8mb compression ... what other ogg qualities are there 
besides 3? Maybe 4? Up to what? Anyplace I could find the full technical 
specs of these qualities? (bitrate & stuff) ? Anyway .. now that i see 
the script is soooooo cool!!! soo configurable .. and yet so easy to use 
... thanks again .. now that I see all this one of these nights and days 
I think my computer will be working hard ... and the awesome thing is 
that the script can be stopped at any time without problems :) awesome 
(I just hope that if I check delete mp3 that's only done until the ogg 
is done in case I ctrl-c). Thanks a lot!!! I think I'll be promoting the 
ogg format :)
