Matt Munroe. About as far away fom soul music as you can get. Nevertheless, I've got a small soft spot for him too. Under rated and under appreciated, he had superb tone and a delicate gift for phrasing. Also copped for some cracking songs from the best of Britain's Tin Pan Alley.
On the subject of MOR stuff, my girlfriend is a huge fan of Doris Day. It's got to be said, she was a great actress, but an even greater singer. I wouldn't call myself a fan, but again; fantastic tone, and gorgeous arrangements. And, yes, I realise she is something of a gay icon, and no I'm not
My other loves include ska and reggae, blues (if it's earthy like John Lee Hooker). Folk does nothing for me, I just don't get it - and jazz is ok if you're stoned.
But...
My love affair with black American soul music goes back 36 years. I may flirt with other musical genres, but I'd rather hear the bridge from Just Can't Live My Life, than anything else on the planet.
