if they did a second greatest hits, I doubt it would include anything already on CR. (ie. mostly '95 onwards). a 2 disc set would be pretty good as it'd allow them to include a few non-singles amongst their newer hits.

maybe something like-

Disc 1:

1. We Weren't Born To Follow
2. (You Want To) Make A Memory
3. Say It Isn't So
4. Misunderstood
5. Captain Crash & The Beauty Queen From Mars
6. This Ain't A Love Song
7. Summertime
8. Who Says You Can't Go Home?
9. Just Older
10. These Days
11. [New Song]
12. Have A Nice Day
13. All About Loving You

Disc 2:

1. One Wild Night
2. Something For The Pain
3. Everyday
4. Lie To Me
5. It's My Life
6. Hey God
7. Welcome To Wherever You Are
8. Something To Believe In
9. Undivided
10. Thankyou For Loving Me
11. Lost Highway
12. When We Were Beautiful
