I have begun using DoubleTwist as my main music app and am wondering how the shuffle command works in practice. If I have 100 songs in a playlist and shuffle that list, will it work its way through all 100 songs and then start over, work its way through and stop, or just bounce all over so that the order might be 4-6-50-4 ... so that some songs play twice or more often before others play at all. I tried posting a similar question on the DoubleTwist web site but got no response. I am hoping some of you experts use the app and can provide an answer. Thanks in advance!
