Unfortunately, that only works with mp3 files.
Since the OP explicitly mentions ogg, I can only recommend foobar2000.
That said, if OP is willing to transcode his ogg (and flac, if any)
collection to mp3, then I agree that mp3gain is the best, failsafe
alternative (i.e., since it tweaks the "global gain" parameter of the mp3
file, virtually all music players will be compatible).
