Awww you don't like the custom startup sound I had my DJ/producer friend make for us?

If you used v2.12 of the tools to run your hack, simply delete the first playlist using PhatNoise MM.
Otherwise, in Windows explorer browse to:
PHTSYS\Profiles\profiles.ini
Double click on the file and it'll open up
Look for 'Startup_sound=' and delete everything AFTER the '='.
Go to file, save.
...and job should be a good 'un.
