Hi,
ATM Info/Buy can't be changed, but instead you can create search script more explained here https://www.mediamonkey.com/wiki/index.php?title=Search_scripts

MM5 will have more possibility and new API should support more online searches

I like being able to look up an artist on Wikipedia or Google, but sometimes I find myself searching for them elsewhere on the internet too.

Would it be possible to add additional search engines e.g. DuckDuckGo, but also any website with a search function e.g. social media; Twitter etc?

So, If I added Reddit as a search:

Right click on a song/artist/album >
Get Info/Buy >
Reddit

And more could be added to the list, something like this:
Amazon
HDTracks
CDUniverse
Google
Wikipedia
Youtube

Twitter

Thank you.
