Better than the 80s AOTY line-up, very fascinating. We have several classic albums, 5 which made the Rolling Stone Top 500 Albums list in the Top 100, with the SNF soundtrack coming close at #131.
The 70s were Stevie Wonder's decade at the Grammys, winning AOTY 3 in 4 years. The one year he didn't win at that time was because he didn't have a new album out which famously made Paul Simon thank Wonder for taking a break when he won.
I'm very fond of CONCERT FOR BANGLADESH because obviously I am a Beatles fan, but quite frankly it won because it was the first of its kind all-star celebrity charity concert and like so many others of its ilk to come, it would be haunted with inefficiently handling/delivering the money to the target needy. (Didn't help when Harrison's people forgot to register with the IRS for a tax exemption and that ) In fact the best moment of CONCERT imo is Billy Preston. Pure awesome. (The worst easily is coked up Eric Clapton really not sure where he is, much less what he's doing.) But no this won't get my vote if we're looking at this objectively.
Oh it's going to be tough for me to pick this one.
