There's not that many female singers who just go by one name. Kiesza is one. This is Hideaway The only other one I can think of is Kesha, but I don't know any of her songs. In the meantime, is it Jess Glynne - Hold My Hand?
Cheryl (Cole) now goes by the one name and there is a disco style song of hers but I can't post it on here as there is bad language in it. It's called 'I don't care.'
