Christina Aguilera, Britney Spears, Jessica Simpson, Mandy Moore

Could you do one for The Cure, The Smiths and Depeche Mode? Thanks!

I can't imagine many others will request this - but Dead Or Alive had a large following in Japan between 85-92ish, yet their chart positions always looked a little lacklustre compared to their (apparent) large popularity. Always been intrigued - maybe someday you could look into it...

A Kenny Rogers analysis seems very needed as he just passed away. He sold a great deal of records in the US and Canada and had several hits in the UK.

please do A P!nk Update' and also Nicki monaj analysis would be interesting to see/ thank yo ufor this website' it is great!

Olivia Newton John, Boyz II Men and New Kids On The Block please!!

Do you consider doing Santana or Clapton this very year?

Exo

They're probably above Led Zeppelin by now.

This is not for an artist, but I think it would be an excellent idea if you made an article about the best selling albums by country (not all, obviously).

Don't think so, Zepp's catalogue sales seem to do pretty well.

Dua Lipa and Pearl Jam would be interesting given both acts have just isuued new LPs.

Paloma Mami please!

Panic! At The Disco.

And not an artist but a blog of the best selling remix albums would be interesting too.

Toto and Toni Braxton please!!

Roxette
