1. get_artist_name(): Dependent on get_top_tracks(), get_recent_tracks(). Sometimes, these two functions return empty string for artist_id. This will cause invalid parameters error when calling get_artist_name(). Solved this by adding artist_name.
2. get_track_tags(): Sometimes, the combination of track and artist does not exist in the database, so no tags will be returned. Need to handle this error. (Also Error 6) (Example: https://ws.audioscrobbler.com/2.0/?method=track.gettoptags&artist=PJ%20&%20Duncan&track=Let%27s%20get%20ready%20to%20Rhumble&api_key=601524a20a9294b649dd49561f64bd53&format=json) Solved by error handling

database.get_artist_top_tags: 输入artist id返回tags
database.get_track_top_tags: 输入track id返回tags
database.get_track_with_tags: 输入list(tags_id) (size: 3-4)，返回包括这些tags的track
databse.get_artist_from_track: 输入track_id，返回artist_id
database.get_tag_id: 输入list(tag_name)，返回list(tag_id)

Use normalizeTag in utils.py to normalize tags when constructing artist_tag and track_tag table.

lastfm api does not return mbid for every track
