DRM-Free Songs from iTunes

Though you can easily use iTunes Music store and directly synch music downloaded on to your iPod of iPhone, the service imposes some restrictions. With Amazon things are somewhat reversed: you get DRM free but also sign in for a less easy-to-operate Amazon MP3 website. It seems that a fortunate combination of the two services would be most appreciated and would answer the needs of all users.
Well, such an answer comes from Advantageous, a Mac OS X script that places “Get MP3 from Amazon” link in your iTunes store, which lets users get a track from the Amazon music store via iTunes. Here's a explanatory video courtesy of CNET.
