That "rice crispy pop" is a bad needle. Vinyl is "anologue" just as silver halide and it is the only way to listen to good music especially on a quality turn table. So Holga would be analgous to a toy plastic record player that plays pop-goes-the-weasel on those thick colored child prof discs. Not that I don't like plastic cameras, if they perpetuate film great. I still need to play with one.
It sounds like you had a good day of it.
