That does not jive with my memories - and I remember WinAmp, MusicMatch Jukebox and Nero Burning ROM vividly.
Heresy! WinAmp was much-loved. This is the first time I'm hearing anything but love for WinAmp - it was the best music player/organizer at the time, and they added Milkdrop as bonus

Now you can make text on a button bold italic, but who knows what that means when you see it in relation to a button that isn't bold italic or is just bold or just italic (other than that the designer has bad taste). I once worked with a designer who wanted control over the focus-caret styling (the dotted line in Firefox/highlighting in Chrome that indicates where keyboard input is destined, which changing has potentially huge impacts for accessibility). Having a UI/UX that grossly visually distinct negatively impacts usability, discoverability, and accessibility, IMO, for very little gain in branding (unless your branding is purposely meant to be "confusingly different from everyone else").
