All the members contributed to writing Queen songs either by themselves or together with other members of the band. Roger Taylor was responsible for quite a few tracks, some of which were considered Queen's greatest hits. One of the songs Roger wrote was "I'm in Love with My Car," which is said to be an ode to his friend, roadie John Harris, as reported by Song Facts.
Another popular Queen song Taylor wrote was "Radio Ga Ga," inspired by his toddler Felix who uttered the words "radio ca-ca," upon hearing a song on the radio that he disliked, (via Words, Music, and Stories.)
Roger Taylor was also responsible for penning "These Are the Days of Our Lives." The song is quite mellow compared to Taylor's other songs, and it would end up having an iconic music video as it was the last one Freddie Mercury would record before his death.
