There are tons of software directories around the web where you could find the answer to that question
One such place which I commonly find myself surfing is the
free software foundation. It shows you open source software that could potentially replace popular windows applications. A quick google search could open up several other websites and then from there you could easily download a few applications to try on for size, and just get rid of the ones you don't like. There are tons and tons of media players and text editors to be found, and I think it might be your job to sort through a few to find what you like.
I'm not particularly familiar with Notepad++ and have never heard of Foobar, but could you possibly describe how Notepad++ "handles tab spaces, and bullet lists"?
