Other is an obtuse catchall it seems that OS X uses that confuses and confounds people more then it helps

I recommend that you download and use OmniDiskSweeper. It will provide a sorted list of what's consuming your space.

If you run it with sudo (As shown below), it will include some system files that it woud not normally have access to scan. That is a more accurate representation of what's consuming your drive. I generally don't go this far, but if you want a complete list its helpful. I think the default option of just running it is just fine and I do that then run manually.
Code:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
