I fight with endings all the time. I just finished, as much as I'm going to do tonite, with a song. . . and I bet I spent a good hour trying everything I could within BB to get a good ending. There has been much discussion here on endings. Most everyone that gets a good one usually imports it into Real Band or something, and fiddles, and edits. The best I can do is do a tag, or repeat, and then do a 4-6 bar FADE. Then at least I don't hear those annoying clashes.
