Obsolescence

With the rise of MP3 players and high-capacity Secure Digital cards the usage of CD's has declined as Digital Audio Players are smaller in terms of physical size, can store more tracks in binary format and don't require the user to carry their CD collection around with them. Online music sites such as iTunes have also contributed to the demise of the CD . Purchasing music on a CD still remains a viable choice for buying new music although due to the decline of portable CD players and the rise of MP3 players users commonly rip the tracks from the CD then archive it, but most often with a loss of sound quality, thus turning sometimes excellent recordings into mediocre sound files.
