**修改建议**
建议加一个生成log的参数，方便上传错误信息

The error occurs in music_dl/extractors/xiami.py line 88 when parsing JSON from a response. Start by examining the xiami_music_info function and the mr response object. Check the raw response text to see why JSON decoding fails. Add error handling or logging to capture the invalid JSON. Run the CLI with -v and the keyword 'beyond' to reproduce the issue.
