I have a hard time concentrating on the lyrics for many of these songs. I think it's because I get so preoccupied at listening to her voice. She's a pro alright.
I tried to follow some of the songs with the lyric sheet on hand and wow, these lyrics are really hard to remember. It's not because they use hard words or anything like that. It's just that they don't seem to have any boundaries. They just keep flowing. Maybe it's her singing style, or maybe it's the songs. Or, maybe it's just me.
