I once got in an argument on the old boards with some guy who was in a huff because according to him, Norwegian singer Ida Maria didn’t sing in her «native accent» (!!!) in English, and he thought that would be much better than «trying to sound American». So many things wrong with that, and the fact that I, as a real life Norwegian, said that she definitely did sing with a Norwegian accent, did not have him convinced.
To your point though, as per my previous post, there is of course not ONE Scandi accent or ONE Norwegian accent when speaking English, but there are many different accents that will easily pass/come across as a Scandi etc accent.
