The opening song is "How Soon is Now" performed by the band "Love Spit
Love". This song is an edited version of the song "Love Spit Love" did for
the soundtrack of the film "The Craft" ("The Craft" soundtrack is
available on CD from, or can be ordered via most record stores (from:
Sony/Columbia; ASIN: B000002BKB)). The first band to perform this song was
"The Smiths", and a large number of other bands (besides "Love Spit Love")
have since performed this song. To the best of my knowledge the song as
edited for "Charmed" is not yet available on CD and/or tape.
