I can repro the OP's top output on an RPi ZeroW by setting gpu_mem=320 in /boot/config.txt.
This gives me about the same total/free/used mem numbers and it also causes kswapd0 badness here.
So, a thought. AFAIK the default gpu_mem value for a 256MB RPi is 64MB while the minimum allowable is 16MB (consult the RPi docs).
The OP could try setting gpu_mem=16 in /boot/config.txt. Prolly have to do this on another host.
I just tried to approximate this on an RPi ZeroW by setting gpu_mem=272 (which is 256+16).
Playing radio stations without issue. No idea whether this would suffice for OPs purposes.
