Audiogalaxy is far from clumsy, it is the easiest damn thing out there. If you can search for a song and click "get it", then you can use it. I have been using their client for a looong time now (since version 0.4xx) and it has served me very well and requires virtually no effort. It reminds me of the "Showtime Oven" infomercial:
"Set it - and FORGET IT!"
It is true that you really need broadband to use Audiogalaxy effectively. The whole web-based thing actually makes things easier IMO but unfortunately AG would be easy to shut down due to its dependence on centralized servers.
