Need help identifying a minecraft song?

I know nothing about minecraft at all. Heck, this might not even be a minecraft song, but this morning i heard a song and it was an original beat. The chorus had something about diamonds in it, but the thing that stuck out to me was that the voice was very high pitched to the point where you could barely understand what they were saying. It sounded like a very young boy singing, but it was not a loud, earrape song. I've looked a bit on youtube but there are so many minecraft songs and i can't find it.

How many stack do have in total?

I'm sorry if this doesn't make sense, I can't think right now. I'm trying to build something in Minecraft that needs 188 logs for what I'm building, but I can't figure out what I would be looking at in a chest. A stack is up to 64 per item. I worked up myself a headache just by figuring out I need 188 for starter like house. How many stacks does 188 up to? 3 stacks?

What is that one classical piece of music?

It goes dooo do do do dooo do do do do do do do do do do do dooo dooo. It's on the tip of my tongue. I know it's used in games as I used to play a game with it in it when it was nighttime (game was similar to Minecraft). The instrumentals go up and down and it kind of sounds like it's from the nutcracker but it isn't waltz of the sugar plum fairy

What was that Minecraft clone?

I've searched all over the internet looking for it, but I can't seem to find a single shred of its existence. All I can remember is 3D-pixel based avatars (one of the presets was Link from the Zelda series), sticks on the ground under a huge tree, required at least a Windows 7 OS and above, it didn't have Craft in the name, and I'm pretty sure I signed up for it. Not to mention it was free, I think.

If anyone knows the name to this game, do let me know. I'm going crazy looking for it.
