I'm going to comment twice, once on the first half, then the second when I get done finding the songs for my own blog;
"Hangman" - Bit too country for my tastes, but to each their own
"Mbube" - This was a nice, relaxing song, and I love hearing other cultures' music; traditional non-folk African music can be hit or miss with me, but this one was a good tune. I'd like to hear her more jazzed up stuff as well ... what? I have American tastes. lol
"500 Miles" - Another nice and easy song I enjoyed. Felt a bit country as well, but it was just the right mix of country twang and folky to get me to like it; soothing.
"Wagoner's Land" - Soothing, yet rebellious in its lyrics. And as a poor man myself, I appreciate her sentiment. Believe it or not, I learned of Joan Baez through the Judas Priest cover of "Diamonds and Rust," which I believe is about her break-up with Bob Dylan. Yes, you read that right, Judas Priest did a cover of her song on their Sin After Sin album. lol
"Chelsea Morning" - I liked it, but the lyrics are a bit saccharine and cheesy. Is that why you don't care for it, or you just don't like her sound in general? The guitar and vocal melodies are actually reminescent of some of the slower, acoustic 90s songs I've heard, probably inspired by her in some way, so maybe that's its appeal to me.
"Someday Soon" - The steel guitar start had me worried this might get a little too country for me as well, but then the vocals kicked in, and I must say, I like her voice. Actually, might be my favorite song so far, so I'm not sure if I'll share your disposition towards her if I find more. lol
I'll be back for the second half.
