Does Anyone Know How To Use Bookmarks in Winamp?

I'm using Winamp version 5.35 to listen to long mp3 files of talk radio and books on tape on my PC. What I want to know is how can I mark where I stopped listening to a file so I can just resume at that point next time I start Winamp up? Some of these files are over 2 hours long, so there is no way I'm going to be able to listen to them in one sitting.

I already know about the Ctrl-Alt-I command to edit a bookmark, and the Alt-I command to make a bookmark, but I can't figure out how to make those commands do anything useful.

Is there another software MP3 player that is easier to use and/or better suited for my needs I should check out instead?

Plain WinAMP doesn't have a bookmarking feature but you can add it through user-made plugins. A search for bookmark" plugins finds two plugins that seem to do what you want (SubTunes and Amarok Plugin).

Thanks I downloaded those plugins and will give them a shot. Can you install more than one plugin for the same thing in WinAmp without screwing things up?
