I've listened to both the Italian and Spanish versions and both are excellent! But because Italian tends to end every word in a vowel, words have a smoother ending, which isn't bad at all. In Spanish, however, there is a good mix of words ending in vowels and consonants. So at least to me, it makes the Spanish version sound more Rock-like because of the harder consonant endings compared to endings that nearly always end in vowels that trail off (sounding less rocky i guess?), as in Italian. Nonetheless, BOTH are way awesome!!
