makes me think of a subcategory question - what album have you bought in the most different media
we should also figure out a special prize if someone bought music both on 8 track and mp3
I actually don't know my answer but i'm going to guess Purple Rain
I never had an 8-track player, and I recorded my albums onto blank cassettes. I have quite a few vinyl albums I bought back in the day that are also on mp3.
