Well actually it’s pretty easy, you can just search SEARCHTERM site: open.spotify.com/show/ - Google Suche and then change the domain.

I think the bottleneck might rather be Spotify changing their API if they notice this. But I guess one could check that easily by requests to spotifeed, if it doesn’t respond the option is removed, or even better the “search spotify” via spotifeed is disabled by default and has to be enabled via settings.
Recognising that this might be a somewhat temporary/experimental feature, would you want this to be in the app? If so I would try to implement it (after resolving my other PR).
