Before discogs I also used MS Access. However once I'd discovered discogs I was surprised at just how many records I'd catalogued incorrectly being totally in the dark about just how many versions of any one particular album. For example there are 4 different 1971 releases of T Rex Electric Warrior (my most treasured album). There were 3 until I discovered mine (bought when it first came out) had an odd variation in one of the track credits so I uploaded it as a new release. Was my 'Discogswhack' for a while but since another 10 bods have added.
