He's a bit too James Blunt really. And the original is hardly pulling up trees with his second album.
The problem with the Bleeding Love cover is it's a contrived piece of hype - he's using Lewis to try and break the charts. It's an increasingly used tactic - "cover a contemporary song in a clever way, pretend it's off the cuff and throw it up on YouTube". The video for it even ties in with the video for the single he released.
And one of the reasons you may not see Simon Cowell putting much effort into promoting Jamie Scott though, is the fact that Jamie Scott's on Polydor/Universal not Syco/SonyBMG
And on Miss Lewis - she seems to be doing pretty well in most countries on minimal promotion. She's only just hit the European trail this last week and a half and is having to play catch up as Bleeding Love shoots top 3 virtually everywhere.
