I agree entirely. I finally got round to buying Delta Machine recently, although early days initial impressions not good. It is a real shame, the pre 95 stuff is simply great, true DM fans know why it has gone downhill but you live and hope(some hope with Playing the Angel for a few tracks). I think DG is a great frontman but just feel nowadays he is trying far too hard with his vocals(he does not need to) in the previous 3 releases.
I too will always defend them and pre 95 loved everything about them, particularly MFTM and SOFAD(e.g. the B-side 'My Joy' is far superior to anything they have done in the past 6 years). As is B-sides 'Sea of Sin' and 'Happiest Girl' from the Violator era.
P.S the Uncut publication/magazine(issued in August) on Depeche Mode is first class, a must.
