I've liked Aimee Mann for a long time. (Way before I saw Magnolia in what, 2004?) She's definitely a mainstream artist, but her popularity among her diverse listeners stands as a testament to her skill. From what I've heard, her songs are consistently good. Catchy, but not too catchy, and a deep sadness and even futility underlies many of them. As she older than most of the artists I listen to, her music is still wonderfully relevant.
Been enjoying her Daytrotter set. (See "Phoenix." Love the organ (?) lines in the background.) Daytrotter is geared towards the hipper indie music genre, so I was quite pleased to see her on there.
