If we take that as a given, pop acts would be the obvious point of comparison - there aren't many great lost Britney, Sugababes or Christina Aguilera album tracks, for instance. But as regards LC!, I'm not sure I agree; apart from anything else, I don't think 'Sweet Dreams' was a single, was it? Wikipedia agrees with me on not. And something like 'This Is How You Spell...', say, for all that the delivery wound me up when it came along early last night, is probably my favourite track of theirs.
