Gary's right - I avoid anything that I'd not do justice to, but the ones I mentioned are cute, pop and very generic.
BTW - who is/are "M3s"??
My Soul Sister beat is a custom track I made from scratch - there was not a style that came close, and I love to play it live on my guitar or Uke, so I make a whole arrangement minus the strumming.
"I'm Yours" is just a Raggae-ish thing
"Highway 20" is another one I play on guitar, so I use a track, or a soft 8 beat
"Just the way You Are" is mostly a slowish Disco number, but I play the bass live to get more of a Bruno feel, rather than a retro attempt.
