I know I have ar least three vinyl copies of DSOTM, and two digital ones. Along with the purchase of the album from Apple Music. They are all different releases of the same album.It's all the multipul copies of each title the makes them start to reallly add up.
At last count I have 15 versions of Pink Floyd - Animals on the hard drive that is contributing to over 3500 PCM albums and another 500 or so SACD's
It just nutting futs.
