OK, maybe you can, but seeing as the fabulous Biscuit Brothers (no, not the fabulous Baker Brothers, that was a movie) just have 3 CDs, they're a ways away from that limit.
In just a couple weeks, though, they'll be ever-so-slightly closer there as they'll be releasing their fourth CD, Musical Farm. Their newsletter (which includes a free download of the math-friendly "Watermelon Song") says they'll be releasing the CD (which includes 7 music videos) on April 2.
Woo. Hoo.
