In reply to SenzuBean:
personally I prefer In a beautiful Place Out in the Country (best track being Amo Bishop Roden)
otherwise, most played album, would be one on my phone, could be
best classical: The Blue Notebooks by Max Richter
best electronic: Patashnik by Biosphere (or the EP named above, In a beautiful...)
best pop/rock: Nocturne by Siouxsie & the Banshees
but if you mean in my life that would have been one of the Joy Division albums, all played countless of times in my younger years, but only listened to occasionally now.
