我了解到billboard每年年末都会有一个单曲年终总榜，想知道2015-2024这十年（包含2015年和2024年）的单曲年终top 10都是哪些歌曲？以及它们的演唱者都是谁？歌曲和演唱者直接给英文就可以。年份不需要带单位，例如2017。请以一整个Markdown表格的格式输出整理后的数据，不要拆分成多个markdown表格，每个单元格都需要按列名要求输出，不得无故省略。
表格中的列名依次为：
年份、排名、歌曲名称、歌手。不要问我任何问题，只需输出结果，输出格式为```markdown{数据内容}```

**Important:** Write your final answer as a Markdown table to the file `/workspace/output.md`. The file should contain ONLY the Markdown table (with header row and separator row). Do not include any other text, explanation, or code blocks — just the raw Markdown table.
