Yes I have used it. It is a bit hit or miss on getting songs matched. I’d say it works on ~50% of the songs in a given playlist. Then maybe 40% “don’t exist in the destination” and another 10% get matched to a weird karaoke version or cover band. YMMV. Their support is top notch though. I was emailing with the creator about the mismatched tracks going iTunes->Tidal and he would make changes to the code, I’d test and report back.
