How does one "Get lost in the music"?

I seem to have lost the ability over the years. Is there a routine you guys follow to get yourself into that state?

My mind is constantly drifting/thinking when i am listening. My equipment is very musical and hiend in nature so i cant blame my equipment for my inability to get emotionally attached.

I dont expect to get into this state everytime i listen, but would like it to happen at least weekly.

Any advice is much appreciated
