Q: Hey, do you like D2/F# or F#-7(b13)
A: if you are asking me which notation i prefer, i would say d2/f#, assuming those are supposed to represent the same chord, which they might not, because there is a chance the other one includes a c# note, it's not entirely clear. which again is why i would prefer d2/f#. but if you need the c# i would say Aadd4 over F# or actually a few years ago i coined a new term for that which is F#-☆
