One record label irks me, as it went through a long phase of not putting the year of release on any of its albums. I pulled out a CD this morning by a band I respect. However, the album's year of release wasn't listed on the CD insert, front cover, back cover, or the CD itself. I wonder if the record label thought that putting a year of release on an album might date it too much in some listeners' eyes. If so, that's misguided, as the music is still the same, and I think most people appreciate having a chronological frame of reference.
Thanks to Wikipedia, I learned that the album was released in 1969. Would it really have compromised the label to have put that year on the product decades after its release?
