Good idea, using Discogs, they probably have a sub link, I'll look into it.Sadly no, but maybe there's a way to find most of them on Discogs. I bought or was given most of the pop/rock Universal releases. And was given a few classical and jazz titles at various events.
It really annoyed me when Universal abandoned the format but much happier now that SDE has stepped in (even though they're not all strictly 'pure audio')... I remember seeing some odd looking French disc releases, in hindsight I should have picked some of those up!
For sure, I own quite a bit of them, but definitely not 100.
