Please give your releases version numbers like software. So when you change a track it could become version 1.01 & then if you re-edit every track it could be called version 2.0. I'd hate to think I still had the best versions of your work when you'd made some changes, especially when you alter a whole set. I'd also like to avoid redownloading a set because you may have updated it, but hadn't. Thanx again.
