The only issue I have is a huge turn-off for me: the background noise. I have sensory issues  and that background noise grates at me. It wouldn't be an issue if it didn't turn itself back up every time the frequency changes. It's incredibly jarring  and I can't use this program anymore until the issue is fixed. Otherwise  it seems like a good program. I'd really like to use it further  so I hope you can fix this issue.
