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.
The point is that it's all just metadata. There's a saying along the lines of "the filename is a really bad place to store metadata". Whether the title is the same and/or the album name as an additional qualifier, it's all subject to data entry which is prone to mistakes.
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...
Record labels are actually quite terrible at providing this. You would assume otherwise because it’s in their best interest. However, I work in the industry and can tell you it’s a ridiculous problem because their is no standard and lots of human effort in cleanup and cleanliness.
You'd think that, but not in my experience. It's not like they are getting ID3 tags populated by Gracenote or some such service. You're also assuming that the streaming platforms do not attempt to manipulate the metadata they received for their own internal policies. See my other comment in a sibling thread for specific examples.
Too much inside baseball experience with the data the studios/labels believe is perfect that when received is far from perfect leaving the individual platforms to deal with it.
