Music perhaps even sooner than what was previously predicted!

Nineteen Sixty-three is pretty much ready for release, and another song (for which i don't yet have a name) is coming along faster than expected.
I have been considering using a version numbering system similar to software to release my music, so that the first public release of a song is titled <song name> 1.0, and then if i make any changes to the song, it would be re-uploaded as <song name> 1.1, and so on.  major remixes would be titled 2.x, 3.x, etc.  This would allow me to improve upon music even after it is released.  Updating of the music would obviously not be enforced DRM-ically because that would be completely unacceptable (not to mention unfeasible).  So it would still be in my best interests to release fully finished songs.
Another idea i have been toying around with is doing 0.x releases, where i could release a song before it is finished so as to get feedback about it before an official release.  At this point i don't think i want to do that, but perhaps in the future that could be something i could consider.
Anyways, that's my thoughts for now.  I hope to post again soon with download links!
