That's an Dsus2/A or Asus4. Yeah that can sound pretty evil. Just quote my post and you can see how I wrote the tab.

This is not either or neither. Partly the nature of the change. Partly where and how it's played or written.
Dsus2 must be new writing and added confusion. In traditional writing and notation a sus 2 is a 9th (regardless of octave). Traditionally, a suspended 9th or 2nd, resolves to the root. Most often called a sus9, can resolve upward to maj or min third. Asus4, I am more readily agreeable, depending on where it is going. The assumption is that A is the bass.
The suspension is D. Normally, resolves to A7, (4th D to C#), but quite frankly, can go anywhere. Suspensions or suspended chords are ambiguous. They are an effect chord with an effect resolution. Naming them is a process of harmony. Where are they going?
