Remixes are my bread and butter. Project 46 remixed both Kelly Clarkson and Pink a couple of years ago, both tracks still work for me. Other than that you got Jump Smokers, Dave Aude, Kat Krazy and Steve Smart & Westfunk who all churn out solid dance floor friendly remixes of popular chart stuff that keeps the more commercial crowd happy. There are loads of other good remixers of course.
Word of advice, check all the remixes of a track and pick one, two at the very most, that you like and ignore the rest.
Someone like Gaga will have more than 20 bloody remixes of her latest track and you don’t want that lot cluttering up your drive.
