Which Queen song was written by Roger Taylor and became a major hit in 1984?

“Radio Ga Ga” was written by Roger Taylor and became a major Queen hit in 1984.

Taylor wrote the song after hearing a musical idea created by his young son. The lyrics reflect changing media technology and nostalgia for radio, while the finished recording uses synthesizers, electronic percussion, and a large singalong chorus.

Queen released “Radio Ga Ga” as a single in January 1984. It reached number two on the UK Singles Chart and became a top-ten hit in many countries. Its handclap routine became especially famous after Queen performed the song at Live Aid in 1985.

The song is sometimes attributed to Freddie Mercury because he sings the lead vocal and helped shape the arrangement. However, the songwriting credit belongs to Roger Taylor. The track appears on Queen's 1984 album The Works.
