I used to have a tee-shirt that said "PURIST SNOB" in big, glittering letters...with a decal of an old phonograph.

I am about as close to 'purist' as you'll find in THIS forum, and yet I'm not really one. I have been known to enjoy... and sing... non-'folk' songs and folk-type songs written recently. All I wish for is some deference to obvious differences in music, so that I can easily find and choose. My default, favorite music to listen to IS the older, traditional, usually by the prolific 'anon', because it just has a different 'feel' than much modern music, and I like LPs, CDs...etc., which can be identified as such.

   There are trends in much modern music...especially 'folkish' sorts... that I do NOT care for, so I am pretty careful in how I spend my $$$$....and I do wince at attempts to 'improve' old, traditional ballads with frenetic pace and volume.......but I do, as I said, listen to and enjoy other stuff also.
Purist? Not really. Picky? Yep!
