This program is a shameless (and illegal) attempt at making money from free software.
It uses the codebase from StreamRipper, an open-source GPL application.
Besides, the program's ergonomy, or lack thereof, makes it a pain to use. The user interface complies with no standard and has a lot of bugs (e.g. you can't save in the "profiles" dialog, which is BTW not accessible from the menubar).
Nevertheless, it does offer the features present in StreamRipper, only in a more limited fashion (because of the limited UI).
It doesn't crash but generally streams just don't start... iTunes integration isn't always *the* way to go!
