I recently ran across a very astute observation that describes the differences between streaming and physical product like CDs and vinyl.
Streaming is consumption, a drink from a fire hose of an infinite amount of product. Collecting physical product is connoisseurship, the act of carefully curating a personal library that is yours forever.
A lot of people do both, of course, using Spotify or another streaming service to discover new music. They then go out and buy what they like for their collection.
RecordRadar makes that a little easier. Once you link your Spotify account, the app will match whatever you have in your collection to retailers that sell
I tried it and I was almost instantly presented with a series of (possibly) collectible vinyl records, many of which were new to me–imports and reissues mostly. This could get expensive.
If you want to give it a try, go here.
