I do this to a point. I'll just hear stuff on the radio, in a store, or on youtube and download it later. One example of doing this is, there's a lot of Russian figure skaters at the rink I go to, so I've heard some Russian music there that I thought was super sweet. In one artist's case, Angelika Varum, I've downloaded like 4 of her albums after hearing one song.

My last instance of doing this, though, I was in West Virginia, and the most listenable station was a classic country station, so I was like "wow, this is kinda great music, actually." Normally I'm not a fan of country, but I came to the conclusion I quite like classic country. So I got a bit of classic country now. This song here captured me:
