Personally, I'd second the record yourself idea. That's what I do. Once I have it down fairly well I record it via webcam like I'm going to upload to youtube. After about 20-30 takes I have it perfect but usually never upload them... The process really embeds the song in your memory though. Record it, then listen to it, and then record it again until you have it how you want it. After a few hours recording one song I pretty much have it knocked I've got probably 200 vids saved on my pc that never got uploaded.
Another thing I do is keep a printed out songbook handy. During the day I practice new stuff that has caught my interest but I keep my binder full of songs beside the bed and every night I spend 2-3 hrs playing all the songs that I have learned in the past to keep them fresh. The ones that I'm currently working out are in the front of the book and they get practice every night! Once I know them really well I'll add them to their proper section in the book (it's arranged alphabetically). It takes me 2-3 days to cycle through the book and then I start it all over again working in more new songs. -Pix
