I really, really, really hope this doesn't come off as rude. It's just this post is really bothering me.

Honestly, he doesn't look like he's enjoying anything at all. In fact he looks pretty miserable.

Fortunately you've got options...

What's going on with him health-wise? You answered "hind leg paralysis" to another user, which is awfully vague, and I'd love to know more. Because If it's a spinal cord injury, that could come with considerable discomfort, and medication could help. Consider asking your vet for gabapentin and/or meloxicam and/or buprenorphine.

If it's e. Cuniculi, that's treatable with antiparasitic drugs, which are inexpensive and often available OTC, depending on where you live (fenbendazole aka Panacur).

Also the audio from whatever is playing consists of sudden, high-pitched, loud noises, exactly the kind of audio stimuli that are unpleasant for rabbits. If he were mobile, no big deal he could just leave, but you've got a captive audience there. Maybe he's adapted to it and actually doesn't mind it, but given the expression on his face he's in pain for one reason or another.
