I'm gonna cheat a bit, and I may be a bit biased, but JB's Live At Ronnie Scott's is not only a killer live set, but a pretty well-spanned career retrospective. The DVD contains more songs than the CD, but the CD still has 16 tunes.
Point taken. Then I'll take back my Yessongs and submit this instead.
Similar to what a lot of other folks have said, I tend to dislike a lot of best-of compilations because they usually have the songs that have been overplayed already. Luckily I never really listened to too much country radio back in the day, so I like all the songs on that one.
