I've been meaning to make this mock-up for a long time now and finally pulled the trigger... Please take a look and let me know what you think and what needs to be different.
1) The first addition is the box where you specify your ownership of the work. The thought here is that we could become more flexible with samples / covers / remixes if we have the data on the back-end. If you don't have 100% ownership of the work, we could simply not run ads on the page and include a notice to developers / animators that this work is not suitable for use in their projects, telling them why.
2) If you have 100% ownership, the next option to appear would be the Creative Commons license. If you check to Allow Commercial Uses, you are inherently giving permission for people to use your work in their games and movies, EVERYWHERE, including console, Steam, etc.
3) If you specify NO for allowing commercial uses, you may want to make an exception for your fellow web artists - this has always been the big grey area with NG because people are generally fine with their music being used in content here. You would be able to check one of three options - allow it to be freely used for web content, contact to discuss, or not interested in it being used.
One thing we may still want to address is an option to generate an actual license that could be turned over to sites like YouTube when they request one.
One final addition is the "Allow downloading" checkbox, which would allow artists to set their music for web streaming only and not allow downloading. This opens NG up to more artists who want to let people listen free but pay to download. And hey maybe we'll let them pay on NG one of these days.
Look it over and shower me with feedback please!
