Sorry, rounded to 1.5 dB. :)

I'd only say that MPC has native support. At least it is stored within
the file structure (and not tagged on as comments), though it seems like
the decoder doesn't do anything with it. Ogg Vorbis uses tags and
requires explicit support in each player, in the same way as Foobar2000
does it for MP3.
