Why does XM radio have online only channels?

[Leros]

XM radio has a few stations that are online only. One of them being channel 42, XM Liquid Metal. This is by far the best station, IMO. Why does it have to be online only?!

I listen mainly to Bone Yard and Squizz. I recently got into the online XM radio and dang, the metal channel is awesome.

Cause theres only so much bandwidth, and they had to make room for every damn mlb game there was. What sucks even more is that a lot of the ota channels arent even online!
