Thought process:

Oh hey... all the outtakes of the 5 disc box set of the Smile Sessions are on Spotify.

Oh hey... there's an entire hour of nothing but outtakes from the Good Vibrations recording. I think I'm going to listen to that.

This is actually pretty enjoyable... you know, for essentially listening to what was a 4 minute song for an hour.

Oh hey... they also have almost an entire disc of Heroes & Villains outtakes. Let's give a listen to that... also enjoyable, although there's less repetition and segueing into other songs a lot.

Hmm... maybe I should stop listening to this for a while so I don't completely burn out on it after a week or two.

That'll work.
