Howdy Kombrig,
And a very Merry Christmas to you and yours, also
Re. the enharmonic spelling - I'm not sure what you mean by "turn this feature off completely". How is it that you would want Composer to allow you to enter notes and show a specific enharmonic spelling?
Re. the mp3 sites - I saw your list of mp3 files above, and figured you might just want a host that gave visitors faster access to the songs, which was why I suggested perhaps using a site like SoundClick or such. Do you have more songs that you'd like to convert to mp3? If so, you can use Audacity to record from a turntable into your computer, then save it as an mp3 file to post on one of those hosting sites. You can get Audacity at
