In my young day, we had to do all our own procrastinating. It's so much easier now.

I'd agree with JeffB that if you have the song sorted in your head before concentrating on the accompaniment (whatever instrument you're playing), things usually fall into place fairly readily. Problems arise where you're trying to set up a complicated accompaniment (to show off your fancy fingerwork) and you haven't put the same effort into fixing the words in your brain. The inevitable conflict for resources can only mean that both the song and the accompaniment suffer.
