Fun fact, Aimee Mann is the only musical guest on Buffy to get a speaking part. That has not a lot to do with Lost in Space, except that two songs from the album are played during the episode. There's a little more to this album than an intersection with nerdom, though.
Lost in Space has a rich, full sound to it. Little wonder, as there's quite the cast of characters. Several songs feature a full compliment of strings, and more.
