I've only tried this once with someone from this forum, more for an experiment (or 'fun') than for any defined "purpose" or occasion. I come up short when it comes to lyrics and vocals, to answer that part of your question, but I have found that once a basic groundwork in the lyrics department has been laid out, I can potentially tweak or even add to that framework to complete the task. I just don't seem to have the ability to start them from scratch (see my "motto" in sig), hence the need for assistance in that field. And as for the voice, I'm still waiting for that tc Helicon thing to come on my platform in BBox, for nothing short of massive digital manipulation could ever hope to make my vocals even the slightest presentable crazy
As for that forenamed experimental collaboration, it didn't quite go as well as hoped, mainly due to different ideas on both ends as to what was actually required. Or, to be more specific, I wanted just "the paint on my fully constructed house", whereas the lyric partner expected to have more leave way to "tear down (or add) to the building" to further complete said "house" alongside the paintwork. So there were different expectations on both ends before going in, a notable lesson in that somewhere I'm sure.
I should add that I'm very much used to working solo when it comes to music, which could also be another way of saying I'm really not the best at working with others. But that's a whole 'nother aspect of this topic altogether...and a very significant one, I' say wink

Just because you can, doesn't mean you should!
