Capitalization of Titles in Spanish

Capitalization of Titles in Spanish
 

I understand there is an excellent thread about capitalization in Spanish already here on these forums, but my question is a little more specific...

I am processing a large number of (mostly) song titles, album titles, etc. and a number of them are in Spanish. I understand the rules of capitalization of English titles (hopefully), but not in Spanish. For example:

El Viaje lo Mejor
El Viaje Lo Mejor

Please can anybody offer me any help as to which (if any) is correct?

Thanks

Only the first letter of the first word, and the first letter of proper nouns, are capitalized for titles in Spanish.

Thank you
