Thanks for the info.
Actually for iOS, you can just buy VIP 绿钻 in S$ with in-app-purchases from Apple App Store.
1 month S$2.98
3 months S$6.98
6 months S$12.98
12 months S$25.98
绿钻豪华版
1 months S$4.48
3 months S$9.98
6 months S$17.98
12 months S$38.98
I have not checked Google App Store yet.
Another potential easier way is to use WeChat. Add a Singapore Credit Card to your WeChat account and then you can receive WeChat Ang Bao in RMB. Pay S$ to your friends here in Singapore who has WeChat money and they can send you to Wechat Ang Bao in RMB. I believe you can buy QQ Points using WeChat.
But I have never tried this myself. I am happy with the free Xiami Music.
Xiami Music vip from Apple App Store
1 month S$2.98
3 months S$6.98
6 months S$10.98
12 months S$21.98
For Paid version, I believe QQ Music should be better since it has more songs.
Wanted to buy the QQ Music subscription, but the app says cannot support paid outside of China.
EDIT: ok, the VPN was disconnected when I tried, once I reconnected, the payment went through.
Any idea what the difference is between 付费音乐包vs禄钻豪华版?
EDIT 2: Replying to my own question...

QQ音乐绿钻和付费包区别如下:
1、绿钻特权是可以听高品质音乐(付费歌曲不能听),免费设置空间背景音乐。付费包特权是听付费歌曲,并不是流量包。免流量服务才是QQ音乐定向流量包。
2、绿钻无非就是发弹幕的时候可以选对话框,音质都差不多,可以换明星皮肤。而付费音乐包则可以一个月内下载300首固定付费音乐。豪华音乐包可以一个月下载500首付费音乐。
3、QQ绿钻可以在线看收费MV、空间背景音乐免费用、QQ客户端显示图标、听歌更流程、下载歌曲更快这几个主要功能。这些功能是付费包不具有的。
