I do the same thing with a shell alias called `SUCCESS`:

  alias SUCCESS='echo -e '\''\n\nSUCCESS'\'' 
    && bash -c '\''mpv ~/bin/kazoo-fanfare.mp3 &'\'' 
    || echo FAILED' # or play sad trombone sound
  # (some escaping might not survive ...)
    

It's an always too-loud and too-annoying "Tadaa!" style fanfare that is very clearly NOT my music, and I will very frequently use it in the context of `make test && SUCCESS` to monitor long-running test suites while I do other work.
