The WebCache.mbl file is created in MusicBee/Appdata/InternalCache when a multiple entry pls/m3u radio station playlist is imported as either a Radio Station or Playlist entry. Upon deletion of said station/playlist the cache with original entries remains, and is not affected by a "Compress Library" operation. Trivial, but it would be nice to have this mbl file included in that operation. Thanks for your consideration.
