Robin writes songs in various musical styles such as Rock, Pop, but you can also find songs that sound jazzy. Her songs are very melodic and I can listen to them for a long time and never getting bored. But Robin's songs are also very interesting regarding the chord structure. They often go to places you don't expect and those surprises make them sounding fresh and interesting. She uses for example chords such as mi7b5, extensions such as a sharp 11 or augmented seventh chords which are normally used in Jazz but which sound perfectly natural and beautiful in her songs.
In Robin's songs you can often find modal interchanges or meter changes and I think that it is really an art to make those songs not sound intellectual. It is not easy to make the listeners not realize that and let them enjoy the music.
Robin's songs are emotional and they have very catchy hooks. Lyrically Robin and her mother Judithe's songs are very deep and honest and they talk about subjects everyone can rely to. But the way they "tell a story" is with the use of metaphors and they usually don't use simple terms such as "I miss you" etc. But everyone can understand of what feelings they are talking. And it leaves still room enough for one's own interpretations. Robin is very versatile and sensitive and she can dig into her emotions and express her feelings and thoughts through her songs.
