I really like exploring music from other countries and in other languages. What I've been doing so far is browsing through different countries' charts and listening to the most popular songs from each country, and I've discovered quite a few songs this way.
However, I do have two problems with it:
1. The most popular songs in a certain country aren't always from that country (they're usually just songs that are globally popular at that time).
2. By definition, charts feature the most popular music in each country, and not necessarily the music that fits my taste.
I think it would be really cool to have an option to select different countries/languages, and then explore music specifically from that country - by genre, release date, etc.
