Belinda Carlisle's new single, "Sun," as posted on SoundCloud by her son, James Duke Mason

OK, not quite a question to "Ask Billboard," but I'll happily take the opportunity to spotlight that Belinda Carlisle has released her first U.S. pop single since the late '90s! "Sun" radiates the same warmth as her great late '80s/early '90s solo hits, with a hook as strong as her best songs like "Mad About You," "Heaven Is a Place on Earth," "I Get Weak," "Circle in the Sand," "Leave a Light On" and so many other great album cuts.

A special touch: she co-wrote "Sun" with fellow Go-Go Jane Wiedlin, who also sings backup on the song. "What would I do without the gorgeous and talented Ms. Wiedlin?" Carlisle posed on Facebook.

"Sun" isn't on the Hot 100 yet, but it is available on iTunes and is receiving early airplay on Sirius XM. It accompanies her new best-of album "Icon," released on UMe.

Check out the fun, and at times quite personal, 25-minute video of Carlisle discussing her new song, and much more, above.
