Wait, the initial query has a mix of download terms and his discography. Maybe they're a fan who wants to know what albums to get. So the proper review should list his best albums, highlight each, mention their significance, and suggest legal platforms like Spotify or Apple Music. Also, address the request for "best" by picking top albums. Need to structure it as a review, starting with an intro about Ricardo Arjona's career, then his albums in order or by popularity, and conclude with a call to support the artist through legal means.
