This sort of record reviewing , where you only review the recordings you like , has been around for a long time.
At another jazz periodical a number of years ago, there was a discussion of this approach. The argument in support of that position was that the number of jazz albums out there was so huge, that it would be silly to waste limited magazine space on them. It seemed more appropriate to bring reviews of the "good music" to the attention of the readers.
Though I understood that argument, I never agreed with it.
