Thanks for feedback!
Maybe I misspoke or the meaning of word "sketch" is different in music world than in visual arts. Judging by responses it is. In 18th-19th and even early 20th centuries, sketchbooks were very popular. The most common ones were in the form of dairies with text, poems (songs too) with hand drawings every few pages. Some of these "drawings" are complete miniature watercolors, some are ink sketches. In both cases-they are complete pictures, that tell a story. They are not "unfinished"...

There are some bands that have 1 minute songs... I am sure somebody will say: Yeah, whatever, they are not "real" musicians, songs must be at least 3:30 minutes or such. To me, these bands, if they produce quality and diverse material are geniuses. In my opinion, if a very short song has a form and a story - is a song... even if it is 30 seconds long (yes, I have heard such songs too smile )

Most of my tunes, do have a form and a story. Some of them are short, but that is not because I got lazy, but just cause I felt they are complete as they are.
What I mean by sketches is that vast majority of them would require significant amount of time to re- mix them properly/ get rid of muddiness as knowledge and tools were not available at the time... And some of them will need musical enhancements such as instrument solos, etc... which I simply can not do well enough with instrument. I am sure that BIAB can solve at least some of these issues.

Seems that for most part people like to move forward... I like to move forward as well. However, I think it is very important to know how and when to go back and re-learn how to ride a bicycle and find that "forgotten" joy all over again.
