"What's Goin' On" was recently remastered on the original Motown/Tamla label for redbook. Actually, several weeks ago Best Buy was runnning a special where you could get both "What's Goin' On" and "Let's Get It On" remasters for $10 (that is total, not each). I nabbed them both, but so far have only listened to them on my PC at work, so I cannot comment on the sound.
