You hear people that say that music is only meant to be heard on vinyl and things like that. Honestly I don't hear that much of a difference, with the exception that CD is flawless and vinyl does have that imperfection that gives a depth to it. Songs like Hear The Bells, The Marching Line, In the end were even more haunting when I listened to them on vinyl! Then, I don't know for what reason but "Fairweather Friend" was the song I appreciated the most on vinyl (along with Hear The Bells!), Vanessa's voice was in a way floating above the music and that made the song even more special. Then there are songs I gotta admit, weren't really different TO ME (like Dear California - which is one of my favorite of the record btw).
EDIT : that brings me to another question. Are the mp3s files sold with the vinyl the same mp3 you'd have if you ripped your CD with iTunes (well only in 320 kpbs!) or are they mp3 rips of the vinyl?
