Case in point: there are two baritone solos in the next Concordia Society concert; the first is a long, plainsong-type chant in a piece called Canticum Sumeonis by Otto Olsson. The other is about two seconds of absolute gorgeousness from Maurice Ravel's Trois beaux oiseaux du Paradis. I auditioned for both of them. It would be really cool to get the Olsson solo because it's meatier, more difficult, and longer. The Ravel is a much prettier melody, though, and I think I enjoyed singing that more.
I think I did a good job at both of them, so it's really up to the conductor and how well the other guys do with their auditions.
