Absolutely not. I could understand 4kids doing it in the 90s, since back then anime dubbing was still a relatively small circle and not many people were aware of it and companies didn't know how to run things. What's TPCi's excuse for doing it today, in the year 2012? Nothing. There is no excuse for replacing an anime's original music--it's the wrong way of doing things and completely ruins the feeling that the original music may have given certain scenes of the show. You're doing something wrong as a dubbing company when people feel compelled to watch the show that you're responsible for in a language that they can't understand just so they can get the full experience.
