I'm not an album buyer in general [I have less than 10 of them], more of an Amazon track buyer.
But I imagine I would probably buy Marcus' potential album [half in good faith / support, half because I believe he's a good singer].
Maybe one or two tracks from Little Mix, Craig, Amelia and Kitty's potential albums, but doubt I'd be interested in the full whack.
Misha's voice grates on me, so nothing from her. And Janet doesn't interest me.
