I recommend you drop what you're doing right now and check out this great list of the "Best albums you've never heard" over at Bullz-Eye. There's a heavy power pop presence on the list, including the great Kontiki by Cotton Mather, as well as discs from The Argument, Fluid Ounces, Jason Falkner, Heap, The Merrymakers, and my favorite disc of 2003, Warren Zanes' Memory Girls. Also featured on the list is Marjorie Fair's Selp Help Serenade, which featured one of my favorite tracks from 2005, "Hold On To You".
Of course, I'm sure most of you have heard at least a few of these discs.
