Do what I and many others here have done. Get a free third party wave editor. Lame, or my favorite.... Wavepad.
http://www.nch.com.au/wavepad/index.html The last time I checked, Wavepad is downloadable and fully functional for a limited time. It shuts down after that time window is up and a popup asks you to buy it, BUT, you can opt to continue to use it in "demo" mode for free. In demo mode it still does everything you need it to do. (trim, normalize, convert, save)
Export the song as a wave, then open it in the editor. In the editor, you can trim the starting count in, and also the ending silence.... you can also use the normalize function to bump it up without clipping and then after saving that edited version, convert it to MP3 at whatever resolution you need.
