Having said that I have used https://ko-fi.com/zzzrod to support (if it can be called that) the dev (the link is from app homepage) as per my personal capacity. Because it is such an excellent service and provided for free and also because it isn't behind subscription. So thought I will share that. But of course it is perfectly fine to use it for free as well if one wants to. Cheers.
I didn't even know TuneMyMusic had a premium service, but fwiw, it's free for the first 500 songs. I've only used it a few times and was pretty impressed at how many services it supports.
