They are not attacking their own sister, they only overlap by half-a-decade (the 80s).
I listen to Journey more than I do B98 because Journey just sounds better. Jingles, 80s and 90s, and NO TEENY BOPPER MUSIC.
B sounds out of place.
Journey also has a much lighter spot load, for obvious reasons.
I will say this--the pop of today is the best it's been in a LONG while.
