It is, and it isn't. As someone who has dipped in and out of collecting British releases for 30 years, I still wouldn't touch a record with no centre. So it's not about what's in the grooves. If I really loved the record I'd get it on a pressing if it existed, otherwise I'd go without. If something was dead cheap I'd buy it without a middle, but it would be the evil steptwin kept in the attic.
