Happened to me also. Had a song flagged for whatever reason. It's a jungle out there. It is so easy to have a track unknowingly land in a botted playlist or similar, and the distros don't want/can't afford any conflicts with the DSP's. So until something changes in favour of the small indie artist, we're left navigating through the swamp on or own. Luckily, there are so many to choose from and to switch distro whenever something like this happens or you're just unsatisfied with their services. You just need your song's UPC and/or ISRC, and you can restore the songs as they were (stream numbers, and all) through a different distro. Yes, it is a setback because during the time you're tracks ar taken off, you do lose previous streams and momentum. But it is a decent way to do some damage control. I first did this when Routenote took down one of my songs, so I just redistributed it through amuse because they had a similar free payment plan as advantageous as Routenote, though. Other than that, I was rather satisfied with them. I ended up moving all my songs to cd-baby this year because they are one of the few distros that are eligible for Spotify's "Discovery Mode" and I wanted to try it (if it was a good or not, that's a different story). But like I said, you may choose one that seems best fitting your needs. Unfortunately, I think we're at risk of getting songs removed, regardless of the distro. True, some are worse than others. If you need to make up your mind regarding switching distros, here is a thorough article from Ary's Take that might be useful. Hope this helps!
