知名唱片公司已升级对AI初创公司Suno的诉讼，指控其故意盗用YouTube上的歌曲来训练其生成式AI音乐模型。美国唱片业协会（RIAA）在最新提交的诉状中，指控Suno非法“抓取流媒体”YouTube上的曲目，并规避旨在防止未经授权复制的措施。诉状进一步详细说明，Suno通过代码访问、提取、复制和下载了受版权保护的作品，并绕过了YouTube的“滚动密码”加密技术，违反了《数字千年版权法》（DMCA）的反规避条款。Suno方面尚未公开其训练数据集，并含糊其辞地说明数据来源，其关于合理使用原则的辩护也面临挑战。

🎵 AI音乐初创公司Suno面临主要唱片公司的升级诉讼，被指控蓄意盗用YouTube上的音乐用于训练其生成式AI模型。诉状的核心指控在于Suno通过技术手段非法“抓取流媒体”内容，并规避了YouTube为防止未经授权复制而设定的加密措施，这直接触及了《数字千年版权法》的反规避条款。

⚖️ 诉讼详细阐述了Suno如何利用代码访问、提取、复制和下载环球、索尼和华纳等公司的受版权保护作品，并绕过YouTube的“滚动密码”加密技术。此举被视为对DMCA第1201条的严重违反，该条款禁止规避有效控制对受版权保护作品访问的技术措施，其应用范围已远超最初的防盗版目的。

❓ Suno一直未能公开其训练数据集的来源，并含糊其辞地说明数据获取方式。尽管Suno声称使用受版权材料进行训练受到“合理使用”原则的法律保护，但此次诉讼通过引用研究表明Suno通过规避YouTube加密技术非法获取了训练数据，对其辩护构成了直接挑战，并与Anthropic的图书盗版和解案有相似之处。

💰 唱片业协会（RIAA）在更新的诉讼中，对Suno的每一项规避行为寻求2,500美元的法定损害赔偿，并对每项侵权作品最高索赔150,000美元。此次诉讼的进展将对AI音乐生成领域的版权问题和法律合规性产生深远影响。

Major record labels have escalated their lawsuit against Suno, alleging that the AI startup knowingly pirated songs from YouTube to train its generative AI music models. In the amended complaint filed on September 19th, the Recording Industry Association of America (RIAA) accuses Suno of unlawfully “stream ripping” tracks on YouTube — a practice that involves turning content captured from streaming platforms into downloadable files — and circumventing measures designed to prevent unauthorized copying. 

The updated lawsuit alleges that Suno “employed code to access, extract, copy, and download” copyrighted works from Universal, Sony, and Warner, and violated YouTube’s terms of service by circumventing the platform’s “rolling cipher” encryption. This circumvention of YouTube’s technological measures “has facilitated Suno’s ongoing and mass-scale infringement,” according to the complaint, and violates the anti-circumvention provisions of the Digital Millennium Copyright Act (DMCA).

Section 1201 of the DMCA states that “no person shall circumvent a technological measure that effectively controls access to a work protected under this title.” Its uses have become extraordinarily broad in recent years, creating roadblocks for everything from unlocking phones to repairing ice cream machines. This lawsuit applies it in a way that’s closer to its original stated purpose: preventing would-be pirates from breaking DRM. Section 1201 has a process for getting exceptions that allow circumvention under certain circumstances, but so far, no specific exception exists for training AI tools.

Suno hasn’t made its training datasets public, and is vague about how the data was acquired. Suno has claimed that training its models on copyrighted materials is legally protected under fair use doctrine, an argument that’s bolstered by at least one court ruling, but not a firm legal consensus. The amended complaint is now targeting this defence by pointing to research from the ICMP publishers group that suggests Suno sourced its training data illegally by circumventing YouTube’s encryption tech. That argument is especially relevant given its similarity to Anthropic’s $1.5 billion book piracy settlement, though that case is currently on hold.

The amended complaint against Suno maintains that the AI music startup fed “decades worth of the world’s most popular sound recordings” into its AI models without authorization from record companies. The RIAA is now seeking $2,500 in statutory damages for each act of circumvention, alongside up to $150,000 per work infringed.
