Well, at least they could make it easy to feedback, like a button on the artist/album page. But it's it really that hard to do it themselves? They are not getting a million albums per day, do they? I'm sure there are ways to improve the process with a little good will.
To some extent yes, but that data is usually sent from record label with the same values for different streaming services. But anyway, don't tell me that they can't at least figure out that there are more than one artists with the same name...
Don't get me started on that. How can a company which core business is content streaming be that lazy is beyond me. I often feedback them the errors, but even such feedback is difficult.
It could check the album names on both sides, for example. And in case of uncertainty, it could make a list of dubious matches. Stuff like that, I guess.
I recently made a transition from Spotify to Tidal and found the suggested transfer service to do the job really clumsy. In my case I've transferred favorite artists and the service was just trying to match them by name which failed miserably when there was more than one with the same name - seemingly it picked one randomly. I wonder how this service would do.
