Streams not syncing properly

Almost every time I stream an album (from start to finish, w/o skipping tracks), stats.fm either misses logging in 1-2 songs or logs in 1-2 songs with the incorrect listening time. This has to be an issue with stats.fm. For example, if i listen to an album with 14 songs, spotify recently played would say “14 songs played” but stats.fm may say i streamed only 13 songs.
