Yes, the EIB network will be able to continue using it.
I like that the same music is being used (at least now during this transition period).
It helps people know that they’ve tuned into the right station.
And that can be specially important for people who travel/vacation and use their car radio.
You hear that and you know where you are.
Also with the shift in hosts, it still makes it clear that this is the replacement (nationwide) and not just at the local affiliate.
For me, time was I’d catnap on my lunch hour and with the radio on, I’d still get periodic updates to the time with the opening theme, the symphonic bumper, etc.
