anointed?

so this weekend i am pondering the anointing of GOD.  as a Christ follower, i totally believe that GOD gives people specific tasks by having them anointed.  this is typically done with some type of fragrant oil. my internal conversation this weekend however stems from a comment that a pastor friend made about a song about a year ago.  he said about revelation song:  "this is an anointed song".   well, i love the song and at the time just thought he was being kind of 'preacher-y' and hadn't really thought about it much since then.  well this weekend i attended 2 very different church services.  the first was friday night - a family friendly, almost geared to kids - service.  the band is ok, but they were also missing some key players, and the congregation was only about 20 (1/2 of them being under the age of 7).  the second service was my regular sunday morning worship service.  the band is accomplished, the lead singer is a vocal major graduate from belmont university, and the congregation was fairly full (about 200 adults).  i give these details because in both services we sang revelation song...and in both services there was an almost tangible presence of the holy spirit during that song.  where as other songs were sung half-heartedly, this one was belted out.  it doesn't seem to matter how well the band 'gels' or how eloquent the singer is or who is in the congregation.  hearts are moved, hands are raised, & tears flow.  why this song?  is it the words?  or maybe the well constructed melodic/harmonic structure?  or could it be that way back in the writing process of this particular song, the composers prayed for GOD's anointing over this piece?  is it possible that GOD poured his Spirit over this melody, over these poetic phrases so that every time it is sung, whether the performance value is there or not, hearts are moved to worship the ONE TRUE GOD.  maybe my pastor friend is correct...maybe revelation song is anointed. 

i'm still processing all that this means, but in 1 John 2:27 it says "the anointing you received from Him remains in you..."  if GOD, through His anointing, can work so mightily through a song...what can He do through me?
