Albums with the smoothest transition
 

I got inspired for this thread from a poll posted in Ayu polls.

I thought a long time before finding the album with the best smooth transition ever.

To me is Absolution of MUSE.

Any other ideas?

It's hard to say...because lots of electronica/dance albums consciously try to blend songs together to maintain a constant, fluid flow of music. An obvious example would be Madonna's Confessions on a Dance Floor.

As for albums from other genres...I can't think of any atm (other than Ayu albums), though you're right, Absolution does have a nice flow to it, as does The Resistance.
