For the purpose you describe -- casually browsing through a lot of versions of a song -- Youtube works pretty well. (They've gone back and forth over the years as far as hyper-vigiliance against possible copyright violations, and at the moment Google's pretty much looking the other way, but that could change.) But if it's truly public domain, you should be able use it however you want -- including performing it in public, sharing it, hosting it yourself -- without fear of legal reprisal. Availability on Youtube is a sorry substitute. It should be here.
And as far as the National Park analogy goes, visiting places like Yellowstone and Crater Lake is a lot less pleasant since Xanterra took over all the lodging and concessions, filling them with low-quality food and miserable, underpaid workers.
