They've released more singles than you can count on all of your fingers and all of your toes. On top of that, they're the biggest-selling girl-band of the century – yes Cheryl and co, they really have sold more records than you! To celebrate this rather nifty feat, we asked Keisha Buchanan to tell us which her favourite - and not so favourite - Sugababes tracks are.
"It's our original single and it has a special place in my heart. If it wasn't for this song we definitely wouldn't be half as credible as we are now."
'Freak Like Me'
"I love 'Freak Like Me' because it was something totally different. This one definitely sets us apart. It started the trend for mixing up old records to make a fresh new sound. We made the whole crossover thing popular which then influenced people like Kylie on 'Can't Get Blue Monday Out Of My Head'."
'Push The Button'
"I think 'Push The Button' did something really special for us and it was really well-received. It showed pop in a different light and was really catchy."
'No Can Do'
"I love 'No Can Do' because it's such a different sound for us. I really like the whole old-school, laid-back sound and it's got a kind of Jackson 5 feel to it which I love."
'In The Middle'
"I'm not really into this one as it's a bit upbeat. I actually wrote 90 per cent of the song so I don't really know what I'm bloody on about! I think it's because as I've got older I don't really relate to the lyrics. It was more of a fun song but I just don't really feel that attached to it any more."
