One of ELO's best. Just like on Out of the Blue every song sounds good but the fact that it's a concept album pushes this beyond other albums that just sound good. I think it edges out Eldorado for my favorite because of the variety of genres represented on Time. My runner up often varies, it used to be greatest hits 1974-78 from Steve Miller Band but recently I've been loving the sound of Fitz and the Tantrums specifically on More Than Just a Dream.
might as well round out my top 7
