I try to learn at least one new song every week, 52 songs a year. Most years I learn about 40 (must be gettin'g old!).
The easiest method for me is to fire up You Tube, listen carefully to the song(s), try to find the lyrics on a Web site, cut and paste them into the PC, then go about picking out a style to match the song. Once I find the style, I usually put the song into the keyboard's Music Finder, or a registration, then go about modifying the style a bit so it's as close to the original as I can make it, then rename the style so it's the same as the song title. With most of them, a couple run throughs and I'll have them down pat, but there are always a few that will take days on end to master them to where I'm comfortable performing the song.
On rare occasions I'll download a midi file of the song, one with embedded lyrics. It makes learning a song very easy. And, of course, you can transpose it to the key you sing in and play along with the song as well.
Cheers,
Gary
