The Doors are the latest veteran act to make their entire back catalogue of music available to download online.
The band, whose frontman Jim Morrison died in 1971, have given permission for all six of their studio albums to be released as digital downloads.
Keyboardist Ray Manzarek says, "The delivery system is what it is. If everyone is on their computer, that's fabulous.
"But although you gain the ease of access, you do lose the sense of an artifact."
Last week (ends23MAR07), SIR Elton John made tracks from more than 30 of his albums available to download digitally.
