SiriusXM and Regional Songs?

I've come to the conclusion that some popular songs were regional hits but were rarely if ever heard outside those regions.

Why? Let me explain. 

I have SiriusXM satellite radio in my car. When the idea of satellite radio was first put forward, I thought one would be crazy to pay for radio when there's free radio over the air. Then I bought a car that came with a year-long free trial. By the end of that year, I was hooked. For one thing, no commercials on the music channels (just a lot of promos touting that). And also, for trips, you don't have to search for good radio stations. You just have to listen to the satellite radio. It does have drawbacks beside the cost. It doesn't go through foliage well so leafy trees can block the signal. And mountains do too. It doesn't work very well when I travel down the Columbia River Gorge toward Portland to see my grandson. But other than that, it's great.

Since getting SiriusXM (used to be two companies called "Sirius" and "XM" but they merged in the hope of surviving), I've heard a few songs I've never heard before. For example, Angry Eyes by Loggins and Messina. And something called Jeans On by David Dundas (whom I'd never heard of). Also Jessica by the Allman Brothers (I'd obviously heard of the Allman Brothers, just not that song). And Lovely Day by Bill Withers. And finally Ariel by Dean Friedman. Never heard of the song or the artist. And the song sucks.

It might be that I stopped listening to Top 40 in about 1977 and switched to what the radio biz called "Album Oriented Rock" or AOR. 

But still, I'm wondering if those songs never made it to the Pacific Northwest where I've lived most of my life (except for when I lived in California when I was in the Army). Another interesting fact is I never heard Free Bird by Lynyrd Skynyrd until I was in the Army.

Have you heard of those songs? Were they hits where you live? Or are they as unfamiliar to you as they are to me? Let me know in the comments below.
