Why don't you have a 192 Bit Rate Paid Service

I would love to hear the music with much more quality, most people now have fast internet so 192 or even 256 bit rate, rather than the 128 would be better. Obviously keep the 128 for free but I would definitely pay a monthly fee to get 192 or 256 just for the extra clarity.

Have you thought about having a premium service?

Thanks in advance.
