Just when you thought Taylor Swift's beef with Scooter Braun and Scott Borchetta from Big Machine couldn't get any more bitter ... she now says they're blocking her from performing her own songs at the upcoming American Music Awards ... but sources connected to Big Machine tell TMZ they have tried to reach a compromise with Taylor, but she's rejected everything and is out for blood.

Taylor says she planned to do a medley of her hits throughout the decade at the AMAs -- which is presenting her with the Artist of the Decade Award -- but says Scooter and Scott claim that would be rerecording her music ... something she's not allowed to do until November 2020, because Big Machine owns the masters.

On top of that, Swift revealed Netflix is making a documentary about her life, but she says Scooter and Scott have declined the use of her older music and performance footage for that project too ... UNLESS she bows down to their demands.

Our Big Machine sources say Taylor has admitted she owes the label more than $7 million and hasn't paid for more than a year. The sources add she also owes BM masters and video content. The sources say Scott and Scooter have extended an olive branch to Taylor, asking her to sit down with them and try to bury the hatchet, but she flatly refused, threatening if they didn't give her exactly what she wanted she'd go public and tell people to attack Big Machine as well as Scott and Scooter.

Taylor says BM demanded she NOT rerecord copycat versions of her songs next year like she's planning ... and to stop talking about them. Or as she puts is ... "be a good little girl and shut up. Or you'll be punished."

Swift says she's at wit's end and doesn't know what else to do, so she's asking her fans to speak out and let Scooter and Scott know how they feel about this.

Ultimately, she says she hopes other artists Scooter manages "can talk some sense into the men who are exercising tyrannical control over someone who just wants to play the music she wrote."

Our Big Machine sources say Taylor's lawyer told them he couldn't contain what she does or what she says publicly about them.
