What a sad world we now live in.......

There is never going to be a winner in the argument whether physical media or streaming is the best sound or which will eventually become extinct. Resurgence of vinyl has proven that. bdp24 is correct. Serious music collectors don't typically shop at Walmart or other big box stores.
Most cities of any size will usually have one or more places that sell a variety of CD's, vinyl, and maybe tapes. I am fortunate to live in Rochester, NY which is a place rich in music history. Several places like House of Guitars, Record Archives, and others offer huge selections.
Stream or put the hard copy in your machine. A personal choice.

I believe the original concern of the OP was how limited the purchase options are for those shopping in the most popular big box stores.
Your opinions aren't without value but not to the point!
