Different names for the same thing

It never ceases to amaze me how many duplicate listings Amazon.com has of so many different CDs.  There's little to differentiate one from the other because the item details merely specify that they're imports.  The UPC isn't even provided for research/reference purposes.  There's like 15 versions of Phil Collins ...HITS album from 1998.  They all have the same product image/details and most of them are being offered used from sellers based in Japan, so one would assume most of these CD issueances are from Japan, but why?  Why in the span of less than 20 years have the Japanese (and possibly other unnamed countries) put this album on CD when it was already available on CD?
Then you look up MASTER OF REALITY by Black Sabbath or most any other CD and they have a two disc deluxe edition, at least one Japanese mini-LP edition, a MFSL Gold CD edition, and...well, I'm speaking hypothetically, I don't even know if that one was ever released by MFSL, but there's 12 editions of that album, many of which have customer reviews submitted for them and Amazon makes it increasingly difficult to figure out which review is for which item.  Unless the reviewer specifically says which item they're reviewing -- which for many years they didn't need to, so they didn't.  What's the point of reading a bunch of people saying "this is one of the greatest albums ever made"/"drop what you're doing and buy this!"/"I really like this album"...I mean, seriously, how does one EXPLAIN what it is they like about a song or album?  Unless you're a technically minded person, which most music listeners are not, thus explaining many progrockers contempt for pop music...
Anyway...
Haven't posted in a little while...Haven't been obsessing about this a lot or anything, just something I wanted to vent about.

I spent way TOO MUCH money this month.  I bought a bunch of CDs, etc....I wrote out my budget for December and I have enough to get Christmas presents for my small circle of family members, but that's it.  I meant to give $85 to God this month.  I'm only at $50, $10 of which is from re-selling osme of the more or less useless junk I had accumulated from online shopping et al...I need to quit this half assed Christianity I'm half assedly practicing.  UGH.
It looks like I will be moving from Southeast Missouri to suburban Atlanta, Georgia in January of 2016.  Another incredible journey.  It's been almost 20 years since I ventured from mid-state California to SEMO.
