It's not about voicing it out. It's about the length and frequency. I can confidently say I can edit those scenes to less than half their length without losing any impact.

2 minutes sounds pretty standard for scenes like this. 4 to 5 is just too much.

And I've said this three times already, but the musical scenes are just part of the problem. There are a lot of panning images and blank scenes littered everywhere. Some scenes are just plain repetitive, like the ones in the bar with rehashed dialogues. These are all really minor things on their own, but added together, they start to make some episodes feel a lot less dense in terms of content, and that's because they are actually less dense.
