Mojang are very careful about updating important textures, all because of the fear lose recognition game against in backdrop of ugly clones. It's strange that they didn't update music disc textures, it looks like they abandoned the black outline of items and flat paint-like textures.

No new or replaced music! just retextured items.

Should work in any version since 1.6
