I had no problems at all with the verification process. In fact, It seems very good and quick for me.
First submission, I had just put some videos from youtube that shows our music group. They asked for more content.
Then I've uploaded some videos that we have from our music group, recorded on higher quality.
Then they asked for evidence that I've authorization over the content.
Then I emailed them asking to take a look on the last live transmission I've made. It was clear that the musicians are the same in the recorded and live videos. Some hours later the channel was activated as verified..
Quick, easy and with no problems at all. Sad that other people are not having the same experience.
