Yes, circa 1981. A Santa Barbara radio station had a local music show and our band was interviewed live. They played 4 of our songs.
We got famous and rich and then retired to Hawaii.
 

I made a song for my wife back in college and it got played on valentine's day on a local radio station. I have had music played on radio and tv ads but obviously nobody knows it is me.

1979/80 Radio play mid-north cost Australia, including weekly promotions for events.  1988/89 air play, various radio stations NSW and QLD, Australia.  Early 1990s music video aired on ABCTV (Rage) and SBSTV (StreetNoise) including interview.

What has it done?
 

 
Obviously the best form of promotion for example, resulted in venues packed to the rafters and sold-out independently released EP.
 
Though the bad also came along for the ride i.e. insomnia, stress, anxiety levels off the charts, security, stalkers and writers cramp.  I never want to go through all that again, but if I had to? Be totally anonymous (some how, but I doubt that can happen)!  Planet Earth is a freaking nut house  
 

Yup. Actually I was sitting in the studio doing an interview for the release, so it was kind of odd, anti-climatic as an experience. I managed to catch it once or twice afterwards. Not much came out of it, but, it's a nice moment nonetheless (and it showed me that I could handle interviews. :P
 
The coolest thing was watching people dancing to my music on the dance floor of a club. A bit like playing live, but actually preferable to me because you can sit there and watch it from a distance, and get to see how people react to your music, not to you or what's going on onstage. 

In my band days, we had a half hour slot on my then local radio station. It was called GWR then, but I think is called something else now. The evening show did a feature on a local band each week, so we managed to get on it one week to plug a 3 track EP that we had just released independently.(Was supposed to have been 4 tracks but ran out of studio time to mix the 4th and couldn't afford any more !). They played all three tracks and filled the rest of the time with band interview & chit-chat. It seemed very cool to the 19 yr old me.
 
Funny thing was, I worked in a factory at the time that had the same radio station playing in the background all the time and a couple of weeks later I was walking around doing what I was there to do and I heard the DJ introduce this "new" tune that he had taken a liking to after being given it by one of the other DJ's to listen to. It started playing and seemed somehow familiar, but I couldn't quite bring to mind why it seeing as it was supposed to be new and figured that it must be one of those that just remind you of something else..then.....D'oh ! I'd lived and breathed the bloody thing for months, but it took me until the chorus kicked for the penny to drop ! The singer also worked there and nobody would believe it was us on the radio until the next time it was on and he had to sing along to prove it was really him.
 
I heard it quite a few times over the following weeks at various times, and in the factory the various old (to me) women who worked there took great delight in singing along (read murdering it) once it became known around the factory floor that it was by "our" band. It was quite amusing to see/hear and I did feel just a little bit famous for a little while.
 
The EP sold enough to recover all the costs and anything over that got spent on tarting up our rehearsal room as it wasn't really worth divvying up 5 ways.
 
 

This wasn't real but radio nevertheless.
 
I knew the owner and only DJ of the local radio station here in rural colorado.
He put one of my tunes up.
 
I heard it at the hardware store. That was a mind blower but:
The Optimod didn't like my final mix/master cause it sounded like toppy squashed lifeless junk.
 
- Do radio mixes man, do radio mixes.

Very limited radio...but still get the occasional "pizza checks" as my wife calls them from movie and TV airplays. Almost embarrassing, really. But we still cash and spend them. Yum.

I have never had my own music on the radio, but then again I haven't composed much since college, but many of my recordings have been played.  Of course since the recording engineer is never acknowledged on the radio, hasn't done anything for my business.  Tomorrow night, April 9th there is an entire show at 7pm PST on XLNC1 radio with all my recordings.  If you are so inclined to listen it will be streaming online at the same time at XLNC1.org.   

My band performed our  original songs live on the radio back in the day.

1967, 1979, 1980.
 
But the coolest one was when I recorded a commercial for my drum teaching. "This is Jim Saad" ... bang boom boom dat, crash, etc.
I was in Santa Barbara in 1970 and recorded it at the local 16 track studio. It sounded great. 
I actually got some students from it!
I taught drums for a living for a few years while I was attending Santa Barbara City College in 1970. Had about 25 students a week. 
 
Later, I moved up to San Francisco and recorded their lessons on cassette. They would hear what I wanted and I would write out their homework.  Then they would record their lesson and send it back.  
I used to go to the post office each morning to see if I got any lessons that day. The checks they sent helped me pay the rent!
 
Sorry I went off track.
