Just browsing tin'ternet looking for x-factor auditions (for me cos I'm good) and came accross https://www.xfactorchallenge.co.uk
this site, you can record your own songs and listen to them, send them etc. Quite a good site me and the missus been having a laugh. Why not record a song and post the link to it?
Not sure how long the free trial lasts but you don't have to enter any payment details.
