I don't disagree with you at all.Although there is no "Ushpizin soundtrack" available, both Adi Ran songs are available on his first CD "Hacharon Sheba'am." These are the actual tracks used in the film.
However, specifically to Adi Ran & the music from Ushpizin ... I'd never heard of Adi Ran until I saw Ushpizin, loved the songs in the movie, and immediately went out to find the soundtrack to the movie. Turns out that there isn't one. I suspect that in this particular case, people really do want to just get their hands on the songs in the movie.
Not condoning downloading at all ... but that might explain the interest you've been seeing in those specific songs.
Sameach music has it here: Ha'achron Sheba'am - Adi Ran
