Up until the 1970s, popular rock musicians began writing and producing in English. In the early 1970s, rock music began to be written using local languages, with bands like the Juan Dela Cruz Band being among the first popular bands to do so. Mixing Tagalog and English lyrics were also popularly used within the same song, in songs like "Ang Miss Universe Ng Buhay Ko (""The Miss Universe of My Life"") by the band Hotdog which helped innovate the Manila sound. The mixing of the two languages (known as "Taglish"), while common in casual speech in the Philippines, was seen as a bold move, but the success of Taglish in popular songs, including Sharon Cuneta's first hit, "Mr. DJ", broke the barrier forevermore.
