Why did ITV stop producing OSTs?

We used to have so many great OSTs produced by itv such as Hum Hai Deewane (Madhubala), Rabba Ve (Iss Pyaar Ko Kya Naam Doon), In Aankhon Mein Tum (Jodha Akbar), etc. Even shows without an OST would use a single Bollywood song for the couple like Dil Ibadaat from Pyar Ki Yeh Ek Kahani. Now, current shows just use random Bollywood songs for the leads so you can't really connect with the pair. So like what went wrong and why did ITV stop making OSTs?
