I don't give rat's a** about Justin Bieber but my wife does. I think I will wait for dbpoweramp mac release
If you can use a PC or Windows emulator on a mac I'd recommend Exact Audio Copy: http://www.exactaudiocopy.de/en/index.php/resources/download/
I whole point for me to buy a Mac was to get away from Windows. Wow, the Exact Audio Copy has won so many award, it is not even funny. I wish they make one for Mac too.
