Actually, I think Boston's "More Than A Feeling" has been played more frequently on U.S. radio than any other song.
I'll have to check and see if this song made the list, but I would make the case that Boston's signature tune had a bigger impact on rock music than any other . . . their title album was really the first ever to be mixed for an optimal sound on the FM dial.
Boston's debut album was the biggest seller ever until a few years ago, maybe still is.
