Well some radio stations do provide information about a song with the right equipment. HD Radio has that capability, as well as RDS (radio data system) which may be found in more modern radios before HD spectrum. That said, many radio stations that broadcast an RDS signal may not actually provide correct information. Pandora, Spotify, Google All-Access, et al., certainly do a better job about informing the listener and as such I'm better informed about the music I now listen to.
