not sure if serious
it is one of the least melodic zelda soundtracks, certainly for console, and having good strong monophonic melodies is one of the biggest things that tends to translate to "memorable". one of the advantages that older guys like koji kondo have over the newer composers who did SS' soundtrack is that the old hardware forced you to write that kind of music
that being said I still think the SS soundtrack is pretty great, slightly better than TP on the whole
