Don't bother downloading this.
In the required-for-setup app called "Playlist Manager," the drag and drop, add, and import playlist simply does not work. At all.
As there was no way to run the app (it auto quits with no valid iStream Playlist file) I cannot give this app a truly fair review.
But until these serious issues are resolved, I feel I have to warn people off.
The app looks promising, but as the support area of the author's website is currently non-existant, there is no tellling when, or even if, this app will be updated to correct the problem I noted.
