I tend to agree. Chic may not have been rock per se, but they were influential and a heck of a lot closer to rock than Run-Dmc or N.W.A (the former being inducted, the latter being a 2014 nominee).
Chic’s drummer, the late Tony Thompson, was a first-rate rock drummer, too. Did some great work with Robert Palmer and also The Power Station.
I swear the first time I heard that Daft Punk song, I thought it was an old Chic tune.
