I must confess that was part of my cunning plan! Just working through the ones I have never heard of on Spotify. Starting with the "A"'s - Alive by Pearl Jam. I would go with the poster's suggestion on that.

What's yours and what has been omitted?
I went for the "Theme from Shaft", disappointed that the only Feelgoods track on there is post Wilko - my vote would have gone for "Roxette" if it...
