I’d have to formally count, but if I have to guess I’d say Los Angeles-based Deorro (formerly TON!C) has more tracks 5 starred in my iTunes library than any other artist. This is in part due to how much awesome music he gives away for free on his Soundcloud page, and in part due to the fact that he’s an incredibly talented producer.
He helped to pioneer the sound that has now become known as Melbourne style house, a fusion of Dutch, electro and tech that is my personal favorite sound in EDM right now. He’s just put out a stellar new single, For President, where he returns to this sound. He’s giving the track away for free via his Facebook page.
