Not sure if this topic is actually trending yet, but it should be! (Thanks, ET) It’s not based on all the songs in my collection, just the ones I have to hand. One song from each featured band (so it’s not just a list of Pink Floyd songs):
Sufjan Stevens – Impossible Soul (25:34)
Like Echoes, it’s like an album’s-worth of songs in one.
Pink Floyd – Echoes (16:31)
I still go absolutely weak at the knees watching that!
