After iTunes shuffle mode insisted on playing "Carinval In Rio" by Judy Roberts for me twice in two days, it dawned on me how well it would segue with Average White Band's "Atlantic Avenue." Both tunes feature vocalists singing about how pleasant the vacation destination of Rio de Janeiro is in a celebratory way without sounding too over-the-top.
I've never heard any radio station play either of these songs, so hopefully, this suggestion will nudge at least one noncommerical station programmer in the right direction.
