So Jealous is the fourth studio album by Canadian indie pop duo Tegan and Sara, released on September 14, 2004.

[8] Writing for Rolling Stone, Meredith Ochs praised the album for its "flashes of brilliance" and said that it probably marks the beginning of a successful career.

She noted the progression from Tegan and Sara's previous "indie-folk" albums to a more "buoyant punk-pop" sound, inspired by 1980s pop.

[4] In his 2005 book Music Lust, Nic Harcourt called the album "a collection of hooky power pop songs that make good use of their vocal harmonies and show them maturing as songwriters and performers".

On April 10, 2005, "Where Does the Good Go" was played in the fourth episode of season 1 of the ABC drama Grey's Anatomy titled "No Man's Land".

The song was released on his debut studio album Teenage Emotions without crediting Tegan and Sara for the sample.
