Obviously ābest power pop band of all timeā is pretty subjective (I certainly think they are though), but Iām guessing that if you Googled ābest power pop albumsā or something, most of the lists that the search threw up would have a Big Star record (or two) somewhere near the top.
None of this stuff really matters though. If you like power pop, I canāt really work out why you wouldnāt want to give them a go. Seems deliberately contrary to me
