No, most 7" versions are more "instant" and better in my opinion. Some cases in point: "Mainline" by Black Ivory, the superior french 7" edit of Sylvester's "Down Down Down", Four Below Zero "My Baby's Got E.S.P.". Playing the entire 12" versions of those tracks bores me out of my mind. And in the example of Sylvester, the 12" version is like a totally different tune and loses all of its punch. Very few tunes gain anything by being stretched out to 8+ minutes. Even an incredible masterpiece and all-time fave of mine like Universal Robot Band's "Barely Breaking Even" gets a bit too much after 10 minutes...
