^ ha, if morning musume released all H!P stuff they'd've died of exhaustion by now. but yeah, the shuffles and subgroups and special units including members from MM has sold a lot that could've been done by momusu.
All of the SPEED members went solo as well. I don't know how well they did. I know it's nowhere compared to SPEED's success. I kept up with Hiro for a while and Takako Uehara.
