Oh yeah, me too. I don't know if it's an S thing but I found my ESTJ boyfriend was far more likely to buy a CD or book to see if it was good, whereas I didn't want to own or store it unless I knew I would be reading and re-reading (or listening to) it. He expressed concern that I needed new reading material when he saw me reading a book over again. He had a monster CD collection that encompassed a very wide variety of music and he was an expert on all of it once he owned it, even if he didn't often listen to it. The Ns I know are all book collectors, whereas with Ss it seems more hit and miss and they may collect for different reasons.
