During episodes 23, 24, & 25, during the Greatful Sound concert, Beck plays a Beatles cover of "I've Got a Feeling." Due to some random licensing issue (Funi didn't want to pay for the rights, or just didn't want to risk a challenge), while the music itself is left intact, the vocal track for the original Japanese audio is replaced with a single generic verse cycling for all 6 minutes or so that the song plays overall (spread over the course over those 3 episodes). Now why they don't think they'd get sued over "playing" the song, but they do think they'd have a problem with including the lyrics to the song is anyones guess. But it completely ruins a somewhat epic moment in the series.
