I noticed the same issue at Tidal and I’ve emailed them as well. Issue below.
Electronic artist Petter Nordkvist
Album: https://listen.tidal.com/album/2375054
Artist: http://www.noll8.nu/ and https://www.discogs.com/artist/494844-Petter-Nordkvist
Is incorrectly mapped to Petter Alexis Askergren
Artist: https://listen.tidal.com/artist/3472 and https://www.discogs.com/artist/173141-Petter
I think any Petter song with the electronic music tag should be mapped to Petter Nordkvist
