Amazon is a great place to purchase MP3 files, but they make Linux users insane with requirements. You can’t just download an MP3, that would be too easy. You have to have the Amazon MP3 player, but there’s no Linux version. So instead they direct us to the Amazon Cloud Player… which required Flash player, also not available in Linux.
JUST GIVE ME THE DAMN MP3 ALREADY!!!
I found that I can download the AMZ file directly, then use the Linux program Clamz to do the download and convert. I got Clamz by double-clicking the AMZ file, and had Ubuntu search for a program that could open it. Clamz puts the MP3 by default into the Music folder in a subfolder that goes with the artist who recorded the MP3.
