You can upload local music without opening VIP.

Upload method: Open the national K song on the mobile phone, click (mine), and then click the three points in the upper right corner. Enter the page, because the uploaded accompaniment songs must be in M4A format, so if your local accompaniment is not in M4A format, click here to download the transcoding tool under "Select File". After converting the song to M4A format, click (Select File). Enter the page, check "I have read and understood the copyright-related matters", and then click (upload).
