[Enhancement] Search engine options

[SebiTalent04]

Just wondering if you could add a list where you can choose the search engine used to find a song. I use DuckDuckGo all the time and searching with Google is somewhat inconvenient.

I think it would be better to use the default browser instead of a hard coded search engine.

[SebiTalent04]

It already uses the default browser, except that the search engine is Google, which may be inconvenient for some people.

Let's handle this as part of #15.

Thanks y'all!
