# SomaFM is a non-commercial radio station project.
#
# Uses a static internal station list. Stream URLs are
# only rewritten depending on bitrate configuration.
#
# Note that only 64bit AAC and 128bit MP3 are guaranteed
# to be available. Most stations offer different bitrates,
# but not all of them!
