I used to like some Michelle Branch songs, and still really like an old concert version of Desperately that I had and Are You Happy Now?, but I took a new listen to Hotel Paper recently- and I just feel like she lacks depth and I don't find her to be a very talented lyricist. You know how we were picking out our favorite lines from Vanessa's songs? Well I think Michelle's songs tend to be a lot more full of fluff and cliche lines. I'm not sure about the Wreckers, I haven't listened to their album, but Leave the Pieces was no lyrical wonder. I mean, it was a cute and catchy tune- I'll give her that, but I don't feel like she has what it takes to last much longer... whereas I think V will be able to maintain an underground following for a long time.
PS- I really like Jessica Harp though. I was a big fan of hers since before she ever even met Michelle... because she was a Hanson fan and people had her website on their sigs years and years ago. Fun fact: Before Jessica ever met Michelle, she went to Hanson's hotel and performed for them in the lobby of the hotel and gave them a demo of her songs she'd written. =P
