# Dirble is a user-contributed list of radio stations,
# auot-updating song titles and station information.
# Homepages are there now, and thus favicons readily
# available. Extra station banners aren't fetched.
#
# It provides a JSON API. Which in this newer version
# is actually speedier, as it doesn't strictly impose
# pagination roundtrips anymore.
#
# Response times are fixed now by overriding the HTTP
# encoding. (A python-requests issue mostly).

# Dirble
#
# Hmm ok, the new v2 API isn't so bad after all.
# It actually contains streaming urls, and even
# station homepages now.
#
# · No idea what status: or timedout: mean,
# just mapped to `deleted` and `status`
# · Stream alternatives are meanwhile scanned
# for "best" format+bitrate combinations.
# · Leave favicons to regular behaviour,
# station banners are not accessible per CDN.
