I absolutely LOVE her riffs. I guess it must be boring singing the same song the same exact way so many times. I personally liked when she changed riffs or added a new one. Whenever I saw the show with Shoshana I'd expect it to be like the last time, but she always made it different. I saw her early in her run, the middle, and nearing the end. To me it was like the more riffs the better but I guess it just depends on your preference.
