Or in my case "Apple-Save", except that Macs no longer have an Apple Key...it's the "Command" Key with a little picture of an intersection on it...but we still call it the Apple Key...
Anyhow, saving is a very important function when working on something very important and laborious. I spent two hours working on a demo for my new album: a song called "Exalted Forever" I had finished it and was just getting ready to bounce it to iTunes when "GarageBand unexpectedly quit", and I never saved it from the very beginning. Unbelievable. So, I spent another hour doing it again (half of the original effort was spent in the creative process: figuring out HOW to do it...now that I knew how I was going to do it...i just needed to actually do it...again)
So now I have 16 songs that I'm going to bring to the table: oops, I forgot about my Heart of Worship cover: 17. Of course, not all 17 will make the cut...the painful cutting process.
Anyhow: people, save your work. don't be silly.
