If vault research is accurate J5 recorded nearly 500 songs during their tenure. There's still 200+ waiting to see the light of day including the album they recorded with Stevie in 1973. Only one tune was extracted, "Buttercup" for a project released shortly after MJ's death. Never having heard any of the other songs,I can see why Motown would shelve it. There's certainly more gold in them there hills though.
