Stairway to Heaven - I don't listen to this often but I do still enjoy it, more than most Zep. It builds well effectively and the guitar solo is good.
White Wedding - pretty good, and I don't really have anything else to say about it.
No Sugar Tonight - this is maybe a little too repetitive, but the instrumentation is nice - reminds me a bit of Grand Funk Railroad's great "I'm Your Captain/Closer To Home" - and it's not unpleasant.
Under the Bridge - a bit disjointed. I like the opening riff and the "I don't ever wanna feel" part, but I don't like the major seventh chord that ends the first and second halves of the verse. The verse itself is fine but pretty generic. I like the coda until the choir comes in. The lyrics are dumb. Overall it's okay.
The Heart of Rock and Roll - not one of his/their best.
Juke Box Hero - I know this is a famous song but I'm not sure I've ever heard it. For some reason it's sillier than I expected, which is dumb because Foreigner do not have a reputation of being overly serious. It's fun enough.
Dirty Laundry - It's a good groove - the keyboard is cool - and Henley's voice suits this thing, but there's not much too it, it's way too long, and the key change is terribly executed.
Piano Man - as a person who has sometimes played pianos at parties and inevitably had this song requested, I ####ing hate it. Objectively it's not bad, and maybe would be good with a less strident singer. Minor points for inspiring the late great Adam Schlesinger to write a great parody/homage for Crazy Ex-Girlfriend.
Cat Scratch Fever - Another one I knew the name of but don't know if I've ever heard. It's not awful but I felt like I'd heard enough of it after two minutes.
