If you purchase a CD (shippable hard goods) product, it is the best quality of music available to the public today — a 16 bit aiff file. If the Samples you listen to on the internet and the songs you downloaded were all 16 bit aiff files, the wait time for the music to load into the internet players and download to your computers and phones would be so long that people (who all seem to now be in such a hurry) would never wait for the loading process. So … in the interest of speed, the quality of the the 16 bit aiff file is converted down to a more Low Res version of the original. Somebody named this an MP3. Most people can’t tell the difference. If you’re one who can, and prefer a better fidelity, buy the CD.
