Were I in my right mind, this morning, I'd do a little more research on Gotta Groove. But what I can tell you without any effort is that they're a record label (in Cleveland) who do a company 7" vinyl Christmas 45 every year (since 2011) to give to customers, artists and employees. To the extent they have any leftovers, they put them up for sale on Bandcamp. And, when the artists will allow, some will be made name your price downloads.
This year's Gotta Groove holiday record is "Winter Waterfowl", a Yuletide murder mystery set in 1983. Seems Drake Srifftail wanted his band to cover "Run Run Rudolph", but the band refused. He threatened to quit the band and the result was....murder. It was murder they wrote. Or was it? I could embed one of the two sides, here, but this is the kind of thing you should really check out for yourself.
The bad news is you're unlikely to score a copy of the 45 (as of this writing, only 5 copies remain). The good news is that you can name-your-price and download it from Bandcamp. It's kinda fun and certainly different.
