EVOLUTION OF MUSIC

Side A: Players of an album made... Vinyl, cassette, CD. Audio output displayed To ears of you and me. Mono in the days of old For output of a song. Better mixing would unfold When stereo came along. Physicality was more Abundant way back when. One went to the music store To buy albums - and then... Side B: ...after years of being sold In shops to you and me, Music nowadays is told And heard in MP3. One's collection can be built Online and through their phone. Consider music as a quilt With tracks together sewn. Who would have visioned or thought That since days of devices, Artists can be streamed and bought At reasonable prices?
