Sadly, you usually have to compromise a bit in relationships. And, if both sides do it, they work much better.
Compromising Stevie? well....depends. do you force him to listen to her? If so, bad.
Do you play it occasionally while he's in the house, while also listening to whatever music he wants? Not so bad...
Do you talk about her constantly? bad - and boring, probably, to your BF.
see, kind of like that....
IN my experience, someone who doesn't love Stevie never will. They might like a song or two okay, but that's about it. So you may have to compromise. But, you're in luck, the chances of a gay man being into Stevie are probably higher than me ever meeting a straight man who likes her.
