To your point about Jagger singing "Start Me Up", I completely agree. If a band records a live album that is essentially a greatest hits package played identically to the studio renditions, I have no interest in it. What I really like are songs whose live recordings exceed their original studio versions. For example, the version of "Rhiannon" on Fleetwood Mac live or the version of "Astronomy" on Some Enchanted Evening are both much better than the originals. In other cases, a song can be completely reinterpreted with great effect - such as Springsteen's take of Jungleland on his live box set. Finally, I enjoy it when artists show their personalities with entertaining banter between songs as Tom Waits does in "Big Time". But I think its true that live albums are no longer as relevant as they once were. I guess they've been supplanted by concert DVDs to some extent. But for some reason I have no real interest in collecting those. I like to watch them once, but don't feel compelled to watch them repeatedly, unlike the live albums that I wore out in my youth.
