I have a "98" powermac G-3 (beige)266mhz running
OS 9.2.2 I need to find out how I can convert my
original songs I have on CD to mp3 format and upload
them to my bands web page for demos?
I tried using musicmatch jukebox, but it won't let
me insert song titles or upload.
I also can't seem to unload the version 5 for version 4
which may be more compatable with my 266mhz mac

I would just use itunes to convert from CD to mp3 format. After converting... you can get info on the song titles and rename as you like.

But to upload them... that is a whole another thing. Depending on where you are trying to upload.... you may need an ftp app of some kind or you may be able to just upload from the web browser as some sites have file management tools setup for the web author that allows uploading without the use of ftp app.
