Scam app
Response from developer
I’m sorry to hear you had a bad experience. First, I want to assure you that the metadata in your files are safe as Groove does not modify the actual files. Second, there is an update on the way that should improve the reliability of the metadata feature. Finally, the app is a one-time purchase which will not show up in your subscriptions. If you’d like, you may contact Apple for a refund. https://support.apple.com/en-us/118223

Thanks so much! I am so glad you've enjoyed using the app. I will definitely add alternate icons to list of planned features.
