>>so, can you name a few tracks that he talks about?<<
Sure, to name some of them...

"One Man Guy" - Rufus Wainwright
"Rain" - The Beatles
"I've Had It" - Aimee Mann
"Frankie Teardrop" - Suicide
"First I Look At The Purse" - J. Geils Band
"Smoke" - Ben Folds Five
"Glorybound" - The Bible
"Royskopp's Night Out" - Royksopp
"Pissing In A River" - The Patti Smith Group
>>Is there a lot more exposition than lyrics?<<
It's not really so much about lyrics, that is to say, a breakdown of the lyrics, as what was going on at the time he heard the song, how it's made him feel and the track as a whole and it's place in the context of the artists career. I mean, sure, he does quote the odd lyric, but not in a "Here we see Dylan constructing a new post-modern lexicon with his use the word 'Lady'" or any of that muso-journo wank.
