I shouldn't have to tell you the music CD is dead, as is every audio format that came before it, with the possible exception of vinyl, the fax machine of the music world. Music is digital, end of story. Digital music differs from any of its progenitors in its lack of physicality; there is no disc that you can put on your shelves, no album liner notes that you can flip through unless of course you create all of that yourself, but doesn't that defeat the point? If you have a digital music collection of over 6000 tracks, you're not going to take the time, spend the money, or use the space to create physical CDs for each of those albums. Still, we need to be able to keep track of our music and that's sometimes easier said than done.
