Also, in my experience it is much more looked down upon to claim you like a band when in reality you only like one song, as opposed to claiming you dislike a band when in reality you do enjoy one song. Personally I think it's one of those cases where you shouldn't argue about it: If they're a little inaccurate on how much they like a band or don't describe it the way you would, who cares; if it's a sign that they're dishonest and fake in general, then that's a problem.
i would agree with the PP. it is completely possible to dig a song and not a band as a whole. that said, i hope this song digs into your subconscious and acts as a gateway drug to Mr. Meloy's eloquent and surreal world. it's a strange and wonderful place. ;)
