I was listening to I need you from the Network. The part I am trying to identify is from 1:58 - 2:14.
I am sure I heard it in another song. Can anyone help?
This section is not a sample itself, although it's always possible it was sampled by another song.
However, I suspect that it's just reminding you strongly of some other song. It sounds almost like a Prince riff to me, similar but not identical to the early parts of 1999.
