Vinyl not Vinyls

I started collecting vinyl records in the 90s because I could pick them up in thrift shops for $1 a piece. Huh? This record with a song I like? To quote Robocop (the good, original one) "I'd buy that for a dollar."  Then through much of the 2000s vinyl versions of records were cheaper than the CD versions. Then they became millennial fetish items and it was like $10 for the CD version, $25 for the vinyl. And you have bullshit stuff now like comedy albums coming out on vinyl.  Really? Your jokes are going to sound better on vinyl than just downloaded?  Also, the plural of vinyl is vinyl, not vinyls, ya know, kind of how the plural of sheep is sheep, not sheeps.
