I really liked Duffy in 2008 and at the time I much preferred Rockferry to 19 - as Duffy and Adele were constantly being compared at the time.
The problem I had with Duffy started when Rain On Your Parade was released. For me, it sounded like a poor man's Mercy and Duffy's vocals had gained this squeaky tone which wasn't as harsh sounding on tracks like Mercy and Warwick Avenue.
Then along came Well, Well, Well and that must've done more damage than good. I didn't liker the song at all. If it was only worthy of being an album track, it would've been the track I skipped on the CD. Lead singles are key in selling a new album. If the lead single puts people off then it isn't gonna help when the album fails to go to #1 and drops out of the chart quickly.
