Jay Robinson has taken an in depth look at the new iTunes LP format and offers some great insight into Apple’s fresh approach at digital music.

Essentially an iTunes LP is an interactive website with music, photos, videos and text wrapped inside iTunes.  What I found the most interesting of all this was the fact that the gorgeous and fluid interface is simply HTML, CSS and Javascript.  Makes a great deal of sense since the new iTunes Store itself is now standard HTML (instead of the past proprietary markup) and is rendered via WebKit, the same engine used in MobileSafari and Safari for your Mac.

The gorgeous CSS transitions and animations that debuted in Safari 4 (along with HTML5 support) are heavily used.  You can take a look at the source by just ctrl-clicking the “ITLP” file in the Finder and choosing “Show Package Contents”.
