OK. I have perhaps negatively exaggerated. However, Exile on Main Street is yet another example of why double albums are a terrible, terrible idea. A strong single album ruined by being crammed with tedious filler to bulk it out to double status. This is the case for all double albums ever made.
Appetite for Destruction was a brilliant single album. You are thinking of Use Your Illusion which was not only a double album but Two double albums split in two and released on the same day.
Physical Graffiti is very good for a double album and probably comes closest to making it work.
