The rapper - who recently teamed up with Queen's Brian May for his song 'Rockstar' - said that he has been listening to a range of different genres since going solo.
Dappy told The Sun: "I listen to everything but I've been listening to lots of classical CDs recently. And I love '80s rock. I want Slash on my next album."
The star recently confessed that he wants Rihanna or Adele to feature on his next single, which is expected to be titled 'Dare To Dream'.
Dappy will embark on a headline solo tour of the UK later this year, starting at Norwich's U.E.A. on September 15.
