Fylm 99 Women 1969 - Mtrjm Awn Layn - Fydyw Lfth

Wait, maybe the encoded part is split into two phrases. Let's try another approach. If we take "mtrjm" and apply a shift of 1 forward: n, u, s, k, n → "nuskn". No. Backward by 5: m→h, t→o, r→m, j→d, m→h → "hodmh". No. What if we take each pair of letters? "mt rj m" and "aw n l" etc. That might not be it.
