if ABB is a great album or not. Then we will know if there are any classics on the album (although it sure sounds like it) and if the album is a classic (could very well be).
Right know we're very happy with a new album in 8 years or so, and anxious the hear good stuff. Maybe overestimate or underestimate (remember how Angie was first received) it
How often will we take the album from it's sleeve 10 or 15 years from now. I remember being very happy with the release of Black and Blue, an album that I haven't heard for more than a year now.
Time will tell!!!.....

You might not have played some of them (albums) for ages, as you have so many to choose from with the Stones, but when you do play them again, you realise how great they all are in their own particular ways
