5 Hol HaMo'ed Pesah 5769
This comes to you a little late, but I just found it myself (Tip Credit: Ben Bresky).
Here's an upbeat version of "Mah Nishtanah?" I would like to recommend. It's from the collaboration of Aharon Razel and Yerachmiel "Rocky" Ziegler. It's the perfect addition for your music collection, and your children's, and it can be downloaded for FREE at Same'ach Music Podcasts.
I am not so "into" Jewish music per se, but I really liked this one!
