On the one hand, I liked how they released CDs with original music. (Ex: Double Trouble.)

On the other hand, I disliked how they didn't release CDs with translated versions of Japanese music that was just as good. (Ex: Part of Team Rocket Forever was in the show but the extended version never appeared on CD like it did in Japan.)

My question is... Why doesn't DuArt do either, except for season themes?
