   Hey guys, flame here. Recently discovered this cool thing, where you override a soundfile by C418 to put your own music on Minecraft! That way, when some guy's listening to 13, you're listening to Deadmau5!

                           1. Convert your music to OGG format.
                           2. Put your OGG file in the streaming folder, found in resources in the .minecraft folder.
                           3. Rename the OGG file to the .mus file you would like to replace.
                           4. Start your game; enjoy your new custom records!

you mean like putting youtube on at the same time, and mute the music but not the sound?
only in-game and harder to do

I'm sure you'll need a special program to do that, of course.

It's much easier to listen to music on iTunes while playing Minecraft at the same time
Audio quality is better than the .OGG format
