Heroes of Might and Magic 4 had some good music, but personally I liked the soundtracks of HoMM2 and HoMM3 better. In that order too. HoMM2 had absolutely amazing music for its time.

The soundtrack of The Witcher is also excellent. But my all time favorites must be the original Age of Wonders and Wing Commander 1.

Battle Macabre, Heartwood Forest and Love & Death from AoW are phenomenal and the briefing music from Wing Commander 1 never failed to strike a chord in me.
