I also obsess over Chopin's Nocturnes. Here's some I found on youtube
YouTube - Wladyslaw Szpilman plays Frederic Chopin's Nocturne in C#min
YouTube - Chopin Nocturne Op.9 No.2 (Arthur Rubinstein)
YouTube - Maurizio Pollini plays Chopin Nocturne no. 8 op. 27 no. 2
Edit: I just realized that Wladyslaw Szpilman, the guy in the first video, was who the movie The Pianist was about.
