If you haven't seen it, check out foobar2000 [1]. It was created by the same dude that made the original Winamp (which is now owned by Yahoo, IIRC).
You might be thinking of Justin Frankel: https://en.wikipedia.org/wiki/Justin_Frankel
The connection is still kind of cool though!
He has nothing to do with foobar2000, which BTW has a very poor view of FOSS.
Foobar still can not do proper crossfading on track change!
