how long do you think an album should be ??
Most of my favorites are in the 40-50 minute range, and that is usually the length that most of the albums that are really important fall in for me
Amerikkka's Most Wanted - 49 minutes
Illmatic - 39 minutes
Doggystyle - 54 minutes
Those are a few examples
If it's over an hour it's usually interesting enough that it feels shorter than it really is, or is just good music that you don't mind
Voodoo - 1 hour 18 minutes
To Pimp a Butterfly - 1 hour 18 minutes
College Dropout - 1 hour 19 minutes
It does start to get a little different when you're talking about other genres though, but even then I do like shorter albums for the most part
