I almost forgot:

The second movement of Vivaldi's Guitar Concerto No. 15!

I've come to the conclusion that almost any slow movement by Sibelius or Mahler is going to be inspired to some degree. They're late romantics, though; they have the right to write inspired slow movements whenever they want to.

The movie Death in Venice used Mahler 5th 4th movement as part of the score. I heard a joke about this where two movie producers were viewing the movie and one asked the other "Who wrote that music". "Gustav Mahler" he was told so the first producer said "Let's get him to write the score for our next movie".
Great music played when JFK was killed.

The slow movement of Tippett's 2nd Symphony in C Major "Adagio molto e tranquillo". Contains an exquisite extended melodic line.

First of all: Brahms: Symphony No. 4, 2nd movement
then:
Dvorak: Symphony No. 9, 2nd movement
Elgar: Enigma variations, Nimrod
Sibelius: Violin concerto, 2nd movement
Brahms: Piano concerto No. 1, 1st movement
Brahms: Piano concerto No. 2, 3rd movement
Ravel: Piano concerto in G
Bartók: Piano concerto No. 3, 2nd movement

A question for confuoco: Are you from Slovakia or from Czech Republic?

From Slovakia, but study in Czech Republic in Brno, city of Leos Janacek

Nice to hear. I've been to Brno recently, and I find it a very pleasant city. Not as breathtaking as Prague, of course, that would be too much to ask, but it's quite interesting in its own way.
I guess it didn't take you long to learn Czech, did it? The two languages are pretty close. I can understand a lot while people talk slowly, but the inn-keepers of Prague have a bad habit of chattering so quickly that all the bonds between our Slavic languages become rather useless... And we always had to resort to English in the end. The same story happened in Bratislava. A pity.

Maybe this is for Non-classical discussion forum:-). Sincerely, I don't find Brno very nice city (however, better than Ostrava ), even though I love it. But it is true, that Brno has great panorama with its cathedral.

I haven't learn Czech, just speak Slovak and it is no problem. Unfortunately, I haven't been in Croatia yet, but from photos and reports I suppose it is one of the most beautiful countries all around the world.

Takže neviem posúdiť, či sú naše jazyky naozaj také podobné, že je možné sa navzájom dorozumieť

Oh, what a compliment! But I can't say - it's surely beautiful, however I haven't seen all the other countries in the world!

I also cannot judge whether it's really possible, but try this:

Također ne mogu prosuditi jesu li naši jezici najzad toliko slični da je moguće međusobno se razumjeti.

Excellent! But I am not sure if I would be able to translate it in reverse direction .

Oh, this is my 100. post! So easy to become Senior Member?

Too easy. And there's nothing beyond that, except if you are appointed an assistant administrator.

Shostakovich Symphony No. 7 "Leningrad" - movement 2.

Dvorak: Cello Concerto ("Slava"/Karajan)
Mozart: VC 3 (Oistrakh playing while conducting the Berlin Philharmonic)
3rd movement of Copland's Rodeo (no joke) (Antal Dorati/Detroit Symphony)
Chopin Piano Concerto No. 1: (Played slowly by Zimermann on DG)
Beethoven: Piano Concerto No. 5: Leon Fleisher/George Szell

The last movement of Mahler's 9th is downright amazing.

And you can't go wrong with the slow movement of the Eroica, either. It's got one of my favorite non-Bach fugues ever written right in the middle!
