It sure is possible to add content. mp3 files are made up of a long
sequence of frames. Each frame is (usually) a self contained unit of
sound with no dependencies on the frames around it. So simply
attaching an mp3 with the same bitrate onto the end of another mp3
will make a new vlid mp3 file.

quick disclaimer: I don't know how to record sound on linux other than
by ripping with cdparanoia.

So, let's pretend you want to create a mix of a metallica track you
like with a crystal method track you just love. Rip your cds with your
favorite ripper - personally, I use grip with cdparanoia and lame. So
now you have two mp3s:


And I think you you combine them using cat:

cat trip_like_i_do.mp3 >> whiplash.mp3
mv whiplash.mp3 whiplash_like_i_do.mp3
