How is it supposed to be pronounced? Is it just gratuitous diacritics? Or should I pronounce it in my native Swedish (where the names makes me think of leaves rather than love)?

(Throwing diacritics on English words look extremely silly to me, since I know how åäö are supposed to be pronounced. It makes something like Motorhead just sound laughable rather than metal.)

The project was started by Norwegians. So I feel like you should apply juuuust the right amount of cheesiness and sort of push that Ø-vowel looong. Not sure if Ruud would agree, though.

I am fairly certain it's a case of https://en.wikipedia.org/wiki/Metal_umlaut

I instinctively pronounce it [løv].

What about the e? If it was Swedish you would definitely not have a silent e, but I don't know if Norwegian might. (On the other hand it is spelled löve, not løve, so arguably Swedish rules should apply.)

I interpret it as English, except with a letter borrowed from other languages.
