Default Are mp3 files heavily compressed?

I have a bunch of mp3 music files and I wanted to save them on a separate hard
drive. I tried using a gui in Konquerer with clicking on the subdirectory with
the tunes then clicking on actions and then create a bzipped tar archive. The
result was a file almost the same size as or just slightly smaller. I did
similar in commend line with tar cf tunes /home/leo/mytunes. I also ended up
with a file that I then gzip and the resulting file was no better. Still no
better compression. I have to assume the mp3 files are already very compressed.
Is this true or did I do it wrong? Is there a better way?
I am still experimenting around with Slackware and other Linux versions and
often get to the point that I can't figure my way back and thus I reinstall and
quite often lose software I want to keep. The music was hard to com by so I want
to save it to a separate drive.

It is true, and you are exactly right about why bzipping or gzipping doesn't
help much.

Not really. They're already compressed. You could re-encode them a lower
bitrate to make the files a little smaller, but in so doing you'd sacrifice
sound quality.
