Absolutely! A Fistful of Dollars, For a Few Dollars More and The Good, The Bad and The Ugly are three of my favorite movies. They have their flaws but so many more strengths, like the music as you mentioned. And Clint Eastwood is awesome. I know some people have issues with the films he has directed, but I don't know how anyone could dislike his acting in these films.

Speaking of Spaghetti Westerns, has anyone else seen My Name is Nobody? It stars Henry Fonda. It's similar to the other three mentioned above but has a lot of comical scenes that seem out of place. However those comical scenes add to the charm of the movie. It has a good story and catchy soundtrack (by Ennio Morricone) as well. Very unique western!
