(313) subject detroit vol. 2 CDR?

[David Barna]

Recently I purchased a copy this disc from an online webstore, not
direct from Subject Detroit. When it came it was a CDR with a slim
case and no artwork. The seller said nothing about it being a CDR and
I thought would be getting a real CD. Does anyone know if the ones
Subject Detroit stocks are CDRs as well? Or are those real CDs with
artwork? Thanks.
