8 tracks were actually damn fine for sound and longevity. I could make my ears bleed cranking Journey and Boston in my brother's 71 Ford LTD with the 8 track. Plus the 8 track is exactly what it's name says: 8 tracks of music laying down each of the instruments and voices separately. It was the first true stereo sound and because of that, you could jam the music without it sounding like unintelligible, crackling fuzz. Before that, the records used fake or "artificial" stereo with the whole recording on 1 track so when you turned it up, it bled together and just sounded horrible-like a radio station just out of tune. 8 track revolutionized portable music, but most important, how we listen to music. If you like to hear and discern each note on each instrument and hear each voice clear and perfect(sorry metal fans-that excludes you guys), tip your hat to the 8 track.
