I've been composing for all genres of music since I became a professional in 1985, writing albums of production or "library music" or writing scores and themes for TV as shown here, in addition to writing and producing pop and jazz music for rpl.
Bruton Music and Chappell Recorded Music Library, part of the Universal group, publish 90% of my Library Music.
