I've been observing the last few days. I really love the new sound. They do go back as far as 1989 with their regular playlist outside of their Totally 80's noon show. During normal playlist hours, I've heard Roxette (Listen To Your Heart, It Must of been Love) and Richard Marx (Satisfy). Lots of Justin Timberlake, Mumford and Sons, Phillip Phillips, Maroon 5, Pink, Fun, Rihanna, 90's Pop Alternative, and some R&B crossover (Chris Brown-With You).
I wonder how much this will change the landscape. B106 is a threat to WNOK, WWNU, WLTY, and even WARQ now. I'd love to see a Rhythmic CHR come in and get things even more interesting!
