Diplo says his hit track ‘Where Are Ü Now’ was a transformative song for him.

The 37-year-old American DJ and producer teamed up with Justin Bieber and Skrillex (real name Sonny John Moore) on the single, and admits he had no idea what a success the song would become.

He wrote on Instagram: “Justin, Sonny, and I started this idea about a year ago and had no idea how transformative a song it would be for all three of us. It’s a statement to where music can go in 2015. We both had detractors but I think the success of both our projects and the song shows everyone should take more chances in 2016.”

Diplo shared a selection of images on Instagram that he feels reflect his 2015, which has been an incredibly successful year for him.

Among the shots was a snap showing him with Madonna at the Met Gala earlier this year.

He captioned the picture: “When I first got a chance to work with Madonna I didn’t expect much to come from it. Maybe because she is one of the biggest pop stars of all time. I didn’t think she would take me serious just another producer working on a huge album. I didn’t expect to make a great friend for life and didn’t expect to be such a big part of her record. She showed me a whole other level of dedication and old school work ethic when it comes to writing. I’m proud of the work we did. Those sessions were some of the most fun I have done to date. I played some shows and shot videos with her later in the year but going to the Met ball with Madonna was a highlight of 2015.”
