My grandmother passed away in 1996 of a fast-spreading cancer. She was non-communicative her last two weeks, but in that time, she left at least 20 index cards with scribbled letters on them. My cousins and I were between 8-10 years old at the time, and believed she was leaving us a code. We puzzled over them for a few months trying substitution ciphers, and didn't get anywhere.My father found one of the cards the other day and I love puzzles and want to tackle the mystery again. Based on some of the repeating segments (many lines start with PST, many end with PAGA, and TYAGF repeats often at the end), I'm thinking they may be song lyrics. She inserts lots of backwards commas, and strange breaks at various points that could indicate stanzas. The back of the card has two numbered lines that contain the same letters. The letters (with line breaks to match the card) and images of the cards are below.PDGNHBOBVPNSNHANAOENCNANHPNCPND,NUOCPNNPNAPNMSMDKBMLPOWP,NAP,]NEENTGBTMLSHHSSSTMALHFFTMOFPANSTP,NIOOIPNTPNROANTRSANTOTTAPOD,PLUADONNOANPBOOLL,PKUASASIMAB,PAGA,]PMOMTAVMAJAMMSSSLLABAPMUTTCTCCATFGSHHILANRNPHTAOLP,]PSTWAAHASIOLAIOW,PSTWALOJTHTPATP,PSTWAGAOKWOCWASAPSTWADVGWAIIRARBOSAO,]PSTWAHPPAAETWW,PSTWAHTPMAESTCWE,]PSTAOUCOOTIOWHAMPAPSTTPDNHA,PSTWAAHAS,PAGA,PSTWAAIEHAPSTWARIEH,]PSTTPAIDNBTVJEOAOU,PAGA,]PSTTOUWWTLWATOUWSLWDSWGOBS,PSTWAHSAHVASASBTATWARHSFAOT,PSTWAHBPITNRSTNOTROUHTTBPM,]PSTVCADAFLAFESJMPLG(the letter C is written here and later scribbled out with a different pen)BGBMBATROURSSASFOHP,]PSTWAGAVWWOA,PAGA]PSTEIFFAWAU.]TYAGFPFG,TYAGFLTMPAAT,TYAGFE,A-TYAGFE,AAA1.

OFWAIHHBTNTKCTWBDOEAIIIHFUTDODBAFUOTAWFTWTAUALUNITBDUFEFTITKTPATGFAEA-My grandmother was alive from 1927-1996and lived in Minnesota.-Her three children were born in the 50s and most music in the house would have played in the 50s, 60s and early 70s.-I do not have any of her other index cards, but my aunts may have some. None of them match each other.-The card does not include anything that her husband recognized, there are no family member initials, etc.-The letters Z, X and Q never appear. Y only appears in the last line.Does anyone have ideas about whether or not these are song lyrics, and if so, any ideas about what song it might be? Or, can you point me towards some magical lyric database that is searchable by the first letter of each word? My family would love to find answers to some of her old puzzles.
