Ambient music as disks

Posting this here under the right topic this time, whoops! Most of the sound tracks in minecraft fall into the category of ambient music for the game. In survival, it is impossible too access any one track on demand. I feel that disks for ambient tracks would be an easy way to add more collectable disks to the game. You could even make each disk specific to a certain structure (mabye 1-3 per structure). This would add more incentive and reward for exploring and discovering structures throughout the world. Several of my friends and I feel this would be a good addition to the game, so I hope others may feel the same.
