Well, ignoring for a moment the flavour of a bridge-substructure symbiont posting, here is an insight of why MP3 was the format to be.
First, back in them olden days when men where still men, women still women and small furry creatures from Alpha Centauri still small furry creatures from Alpha Centauri, a normal MP3 players capacity was not rated like today in GByte but in it's lower cousin MByte, say, 124 mbyte or ram. Which meant a lower quality rip could spell the difference of having 30 songs on it, versus only 10. Also, back in them olden days, when the mp3 players still either ran on steam power or illegal plutonium charges, the soundchips were even worse than what they are today.
Also they were never meant to give the ears of audiophiles a sound orgasm, but they were merely meant as replacement for the walkmen that used tapes (yes, some people would have to look up what tape or audio cassette means nowadays). If one was into aural sex, they usually did that in their seclusion of their home where they had a stereo system.
