I can't comment on radio friendly seeing as I've never once heard either band on the radio ever. But Rise Against's newer stuff is very....nothing compared to Sufferer and Witness and everything prior to that...Gaslight Anthem has put out solid records and their "worst" one is probably their most punk record. In my opinion, of course xDD
I don't know, I never cared for Rpm as much as Siren Song. It's been a while since I've heard either one though.
Yeah, I've never been a Gaslight Anthem fan really, but I generally hear their fans like only their new stuff or only their old stuff. You've never heard Rise Against on the radio though? Man, they were all over MTV and radio stations that I listened to when "Swing Life Away" came out. "Give It All" did really well off of that album as well, and they had about three pretty big singles off of TS&TW
