Ask HN: Do weird domain names naturally just do better?

Asking for a friend:

In a typical audio setup, there are two components wired to a stereo system that produce sound. The exact term for these components escapes me at the moment. However, if we take the singular form of this term and append ".app" to it, it forms a domain name that my acquaintance owns.

Despite the domain's relevance to audio, it doesn't seem to attract much traffic, according to my acquaintance. It's almost as if a randomly generated domain name like ub89u98u2j39u492u.com would garner more attention, which is a bit perplexing.

This situation has raised some concerns. Could it be that the domain name is simply not appealing or memorable enough? I'm interested in hearing your thoughts.
