Just to document this, here is an example of retagging (original file was an
ID3v2.3 file and can be found on attachment #69586):

gst-launch filesrc location=test4.mp3 ! id3demux ! id3v2mux ! filesink
location=test4-retagged.mp3

the original tags look like this:

# gst-launch-0.10 -t filesrc location=test4.mp3 ! decodebin ! fakesink
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
FOUND TAG      : found by element "id3demux0".
