I definitely agree that it's "magia o realta' " this makes total sense in the context of the poetry of the lyrics here. "I don't know if it's magic (magic or fantasy, the fantasy of the movie screen) or reality (this time-space reality I'm living)."
Also, Josh Groban's first language is American English, as such, his rolling of his Rs in Italian and Spanish is somewhat minimal at times, sounding more like a Spanish letter "de" or "ele" now and again. This being said, I love Josh Groban. It takes a lot of guts to take on these big Italian songs like "Se".
