Madaming backmasking issue sa mga kanta ng beatles. mga hidden message daw na nagbibigay ng clue na patay na si paul mccartney. simple lang yan, pinatugtog ng pabaliktad yung kanta, yung boses nagkaron ng katunog na salita na ginawang issue at sineryoso ng iba.
sa "revolution #9"..."number 9" in reverse is "turn me on, dead man"...tapos meron pa silang hidden track sa sgt. pepper's, yung "inner groove"...nalimutan ko na kung ano sinasabi nila sa regular version, pero kapag binaligtad mo, maririnig mo "we'll f**k you like we're Superman", o "will Paul come back as Superman?"
to answer the question, backmasking is all hype...it's anything you want to imagine the backwards lyrics to be...though some coincidences can be creepy...
for example, play one line from mutiny's "ibaon mo sa limot" in reverse...the line "sino bang nababaliw, ako ba o ikaw?" when played in reverse sounds like "ako'y nababaliw, ikaw din!"
then there's "stairway to heaven" played backwards...in all fairness some of the alleged backwards lyrics sound accurate, but again...just a creepy coincidence, IMHO.
