Where to download drama OSTs?

Does anyone know where I can download korean and chinese drama OSTs? I used to use https://kdramaost.com/en/ but they haven't been updating their website lately. 

Please help!! I really wanna download the OST for Immortal Samsara and Love Like the Galaxy haha and I don't want to use a Youtube to MP3 converter since quality isn't as great and I haven't found high quality videos to convert 

I usually just download it via youtube. Haha...
