I recently created my second resource pack and I changed the music. whilst playing minecraft, though, it played the default music instead of mine. it is an ogg vorbis file and it used to work in the 1.6 update.
I expected the music that came on to be my music.
what actually happened was it started playing the default tunes instead of mine even though I had selected my resource pack.
this bug happens every time a piece of music plays when you have a resource pack (with music) on.
