8:16 PM PT -- Taylor just won Artist of The Year, and said the last year has had some of the best and hardest times of her life. While she never mentioned Scooter or Big Machine directly, it's hard to imagine she wasn't referring the situation.

It's also worth mention that Taylor's outfit at the beginning of her performance had the names of her old albums ... a not-so-subtle dig at Braun.

Taylor Swift could not have been more gracious accepting the AMA "Artist of the Decade" award ... and there wasn't a peep about her old songs, Big Machine or Scooter Braun.

Taylor sang most of her biggest hits, including "Love Story," "I Knew You Were Trouble," and "Shake it Off."  What's interesting ... she didn't sing "Bad Blood," or "We Are Never Ever Getting Back Together" ... the latter could be a metaphor for her relationship with Big Machine, so not singing it was interesting. She opened the set with her new song, "The Man."

Swift got huge applause and thanked just about everyone in her life, but no mention about her raging dispute with B.M. and Braun.

Our sources tell us ... Taylor and/or her team have not met with Scooter and/or reps from Big Machine ... this after Scooter's overture Friday morning.  We're told there are no plans to meet.
