What I do lately is first try to find a good midi file to start from (for free). If not then I recreate the song with BIAB to a somewhat close rendition. That's 'cause I'm cheap and BIAB is rather fun for me. As long as it has the same general feel, which often relies in the drums and bass, then I can usually ad-lib the rest with my guitars and vocals.
For starting with a good midi file I often resort to SampleTank 3 and the Studio Instruments that came with Cakewalk Music Creator 7. Which I think are the same that now come free with BandLab. Then I have a few free piano VSTi plug ins and I still user a few instruments from Cakewalk TTS-1 as needed.
BTW, the free drum midi's from Groove Monkey come in very handy at times.

Does the noise in your head bother me ?
