re: Video explains the world's most important 6-sec drum loop

I don't think the pattern can be considered intellectual property because it's such a grey area. There are so many instances of snare on 2 and 4, kick on 1 and 3, with 8ths on hi hat. Although that is SO basic (and perhaps old) it could be argued that is public domain, and a pattern such as this amen break should be intellectual property.

I don't really have a firm stance here.

The recording I feel should be considered intellectual property. If you have to have a sample of that particular recording for your work royalties should be paid in my opinion.

I can understand why that's not the way it is I guess. You'd have an abundance of disputes about whether or not money should be paid to the original artist and law can't be counted on to simplify itself such that it wouldn't be over burdened to sort through that.
