Import from a directory of playlists

[knichel]

I have been working on modifying the script to accept a directory of playlist files. If I make a playlist and run it through the original script, it works. If I copy it to a second file with a different name and run it through my version it works and imports both playlists. However if I I export 2 separate playlists, it works on the first but fails on the second with this error right after the print "Matching Songs..." Traceback (most recent call last): File "test_gm_playlists_importer.py", line 145, in main() File "test_gm_playlists_importer.py", line 115, in main matched_songs = matcher.match(queries) File "/usr/local/lib/python2.7/dist-packages/gmusicapi/gmtools/tools.py", line 393, in match res = self.query_library(query, tie_breaker, auto=auto) File "/usr/local/lib/python2.7/dist-packages/gmusicapi/gmtools/tools.py", line 311, in query_library next_results = self.query_library(query, tie_breaker, current_mods, auto) File "/usr/local/lib/python2.7/dist-packages/gmusicapi/gmtools/tools.py", line 311, in query_library next_results = self.query_library(query, tie_breaker, current_mods, auto) File "/usr/local/lib/python2.7/dist-packages/gmusicapi/gmtools/tools.py", line 309, in query_library raise self.TieBroken(tie_breaker(query, results)) TypeError: 'staticmethod' object is not callable

I think I'm going to do a quick overhaul on this script while on the train =)

I'll definitely include this feature, but probably in the form of multiple input files, so you could do something like $ script.py my-dir/*.

My implementation simply took the folder as the input and anything in the folder is used.

I have started working with this again after having to step away for a while. I am now trying to get the single import to work and I keep getting 0 matches. Can you look to see where I might have an inssue?

get_all_songs is broken at the moment: https://github.com/simon-weber/Unofficial-Google-Music-API/issues/221.

I'll check this out once it's working again.
