I miss that network discovery as well, as well as the quasi-random element to it. Nowadays I get my kicks by searching for, say, Albanian rock (I don‘t speak Albanian), whatever was trending in Indonesia (I am not from there), who is the national poet/singer of France (I am not French), what was playing on Peruvian radios in 1985 when I born, etc.

Edit: it‘s also a great way to meet other countries/cultures, not only other great music. For example, this is how I got acquainted with the beautiful Wolof language from Senegal and even with traditional regional music in Brazil (where I am actually from) I would have never been exposed to otherwise.
