I'll grant that quite a bit more "volume" can be stored in an MP3 music collection, but the audio quality isn't close to comparable. Whether by means of a needle "scratching a vinyl surface" or a magnetic head 'reading' a magnetically encoded tape, the resulting sound is analog, which proper playback of music should be. No matter how many times analog music is oversampled to produce a "clean" digital recording, such a recording lacks--to the human analog ear--the proper instrumental and vocal sound quality. That is one of the reasons there is a resurgence of interest in vinyl recordings and the equipment upon which to play them.
