What album have you bought in the most different formats.

PF, DSOTM. I have the MFSL CD and LP, SACD, original Harvest pressing on LP, 3 reissues on Both LP and CD, Blu-Ray, Immersion box set, colored white vinyl LP, Russian Version LP and CD. HD Tracks download.

@stereo5 ,

"That makes 16 versions. Is it a new world record?"

It might be. The only other album I can think that might have as many versions is Kind of Blue, but I’ve not heard of anyone having 16 variants of it! (unless there’s someone over on the Steve Hoffman music forums)...

I mean I must have had 3 versions of KOB and 3 of DSOTM and 3 of Led Zep IV (the best was the last).

Maybe this is another trait of being an audiophile, multiple copies of the same album. Although I guess it’s partly unavoidable if you’ve been around long enough due to regular changing of the formats.

Just how many have there been?
Here’s the ones that I know of.

78

LP (45 rpm LP)

Cassette
R2R

8 track

CD / SACD / DVD - Audio / Blu-ray

Minidisc

MP3 Download / HD download

I wonder if we’ve finally reached the end of the format road?

One more format would have been the short lived video disc, not sure about music on them.  I was not trying to make this a contest, LOL.  It is more about a favorite piece of music and evolution of formats over time.  Being 72, I have been buying music for 60 years... how did I get this old?
