Worship vs. Songs

Talked breifly to 'Mr I loved the music but not the songs' last night and asked him to explain his thoughts on the issue. It was basically what I'd heard from others and though about myself, that is it appropriate to sing words which you don't agree with/live out/feel for yourself as worship to God? (feel free to correct me AN if that wasn't what you meant).
As a muso though, we don't really have the option, we have to participate. Although, it's easy to hide behind the piano just go through the chords taking my own meaning from the music rather than the written words.
The bass player from SYG suggested we should all think about the songs and try to understand where the writter was coming from when they wrote the songs. I'd never thought to do that before and to me thats a more proactive and worshiping thing to do than to just sit out and not participate. At the risk of sounding indivdualistic, I would even suggest we find our own meaning in the words- you don't have to agree with whats being sung but find where you stand at that moment and be aware of that and bring it to God. Being honest both with yourself and God. If worship has to do with respect- isn't honesty a large part of that, but also being active in worship and not just taking the position 'nup don't agree so won't participate'. (not at all saying thats what you meant AN).
