They have other good songs too ("A Minute Without You" is my favourite I think). "Middle Of Nowhere" is actually a pretty solid album overall. Produced by The Dust Brothers of "Odelay" and "Paul's Boutique" fame.
Hanson were really only a "boy band" in the fact that the members of the band were all boys when they achieved success. They did need a bit of industry help to get where they were at first since they were still kids after all (Middle Of Nowhere has outside songwriters helping flesh out most of the songs), but once they became adults they just became a regular band. And they still do good work.
