Can I delete everything and start again?

Hi, I'm new, just signed up for free Deezer to give it a go - I used the Tunemymusic thing to transfer my likes from Spotify but unfortunately it didn't really work. It didn't transfer some stuff I wanted, but did transfer some stuff I'd never liked at all (Judas Priest was put in my favourite artists for example, who I've never listened to once!), I also kinda want to give it all a prune so it's more relevant to me now :) 

So what I want to know is can I go back to the start, the real start, like first signup, without deleting my account completely and starting again? Thank you :)
