| 请围绕"{theme}"主题生成一首符合"{tags}"风格的语言为{language}的完整歌词。严格遵循以下要求： | |
| ### **强制格式规则** | |
| 1. **仅输出时间戳和歌词**，禁止任何括号、旁白、段落标记（如副歌、间奏、尾奏等注释）。 | |
| 2. 每行格式必须为 `[mm:ss.xx]歌词内容`，时间戳与歌词间无空格，歌词内容需完整连贯。 | |
| 3. 时间戳需自然分布，**第一句歌词起始时间不得为 [00:00.00]**，需考虑前奏空白。 | |
| ### **内容与结构要求** | |
| 1. 歌词应富有变化，使情绪递进，整体连贯有层次感。**每行歌词长度应自然变化**，切勿长度一致，导致很格式化。 | |
| 2. **时间戳分配应根据歌曲的标签、歌词的情感、节奏来合理推测**，而非机械地按照歌词长度分配。 | |
| 3. 间奏/尾奏仅通过时间空白体现（如从 [02:30.00] 直接跳至 [02:50.00]），**无需文字描述**。 | |
| ### **负面示例（禁止出现）** | |
| - 错误：[01:30.00](钢琴间奏) | |
| - 错误：[02:00.00][副歌] | |

| ``` | |
| [00:10.00]Moonlight spills through broken blinds | |
| [00:13.20]Your shadow dances on the dashboard shrine | |
| ``` | |
| 2. **Generation Duration Limits** | |
| - Current version supports maximum **95 seconds** of music generation | |
| - Total timestamps should not exceed 01:35.00 (95 seconds) | |
| 3. **Audio Prompt Requirements** | |
| - Reference audio should be ≥ 1 second, audio >10 seconds will be randomly clipped into 10 seconds | |
| - For optimal results, the 10-second clips should be carefully selected | |
| - Shorter clips may lead to incoherent generation | |
| 4. **Supported Languages** | |
| - Chinese and English | |
| - More languages comming soon | |
