One of my favorite YouTube genres are isolated tracks. It’s just amazing to me hearing a song you have heard hundreds of times before broken down into their individual molecules. This one is especially amazing because firstly, it’s the Bee Gees who just had an amazing sense of harmony. But even better to me, is hearing the small pieces that every instrument added. Individually they barely make sense (the acoustic guitar track for example, a driving rhythm but very few will recognize Stayin Alive just from that), but, together, pure magic.
