Have you noticed that the theme ‘musics’ for Sony Max, Sony Max 2 and Sony Aath are very similar to the previous ones? They are still using the D major, G minor and A major chords, respectively. Of course, SET’s music is completely unchanged, while Sony Marathi has changed only the chord (from G major to B major) while the notes are the same.
On the other hand Sony Sab has completely changed its theme music from the previous one (from G# to C major) and I think it is my favourite out of all the new channels. Sony Wah has also changed its music from the old one (used by Sony Max from 2012 to 2015) and Sony Pix as well.
