Kevin MacLeod's site offers free royalty-free music and printable graph paper PDFs.
HN commenters point to it as a source of royalty-free music for games, videos, and hobby projects, run by a single musician.
Very cool resource and there are some great tracks here. I'm excited to see how you expand the library to accompany all kinds of different projects, even beyond games.
I'm quite a fan of royalty-free music, actually I just finished up a project using 100% royalty-free music from Kevin MacLeod (http://incompetech.com/). He uses a creative-commons license for all of his work, but makes the bulk of his money through private projects brought on from exposure.
Our project was for an immersive reading experience for The War of the Worlds, which meant we needed lots and lots of different types of music for all the story arcs. Shameless plug if you want to check it out: http://e-mersiv.com/apps
Again, I think you could definitely have a market for more than just game devs out there, your pricing model is attractive enough to be used for short videos, ebooks, etc.
Music copyright is incredibly messed up, even compared to the rest of copyright. I was doing research for a project I'm working on, and it's nearly impossible to determine if any 20th century recording is in the public domain unless the author explicitly declared it as such.
YouTube (and by extension Google) are actively making this worse with automated ContentID. There are many documented cases of author-released public-domain or creative commons work being claimed by other people [1]. Create a false entry in the ContentID database and issue takedown notices to the original creator and anyone else who used the music. Even if you get caught you can drop the claim and still walk away with the money you made off of their videos.

For my last year of classes, I made something similar, though for a lower cost.
I used http://incompetech.com/graphpaper/ to make a custom dot grid to accomodate my large handwriting, imported it into InDesign to create 200+ numbered pages of the grid and then added a few pages front and back of reference items. Finished up with a color cover of my own design, and then sent the resulting PDF to an online printing service, Lulu, and the resulting 8 x 10 notebook was quite nice.
It didn't have the feel of a Moleskin but the spiral binding was pretty resilient to the daily abuse, the thick cover also held up perfectly, the paper was thicker than normal notebook paper, and it was nice having a notebook which fit my writing style perfectly. Total cost per book was around $15.
Eh, I think it's just a common mistake, and I corrected them because it's a pet peeve of mine, not because I think it is a big deal. Your line of thinking is not new to me though, and if "could care less" is sarcastic then I would argue it is particularly ineffective sarcasm (see: http://incompetech.com/gallimaufry/care_less.html).
Does it include music from oft-used music sources in YouTube videos such as AudioMicro and Incompetech[1]? I'd guess it's not really possible on the AudioMicro front as they're paid-for music that'd cost you a fortune to index but may be worth adding the latter

Come for the graph paper, stay for the snark. Go to the Grid Dots page[0], and...
I'm going to guess you're really into pens. Not an unhealthy amount... but more than most.
It's like the web page sees into my mind!
