The Windows 95 start-up chime has been added to the Library of Congress
The Windows 95 start-up audio was composed by ambient music pioneer Brian Eno. According to the blurb from the Library of Congress, the final sound clip was twice as long as Microsoft's engineers had requested of the composer. But they went ahead with the chime because they felt it "conveyed the sense of welcome, hopefulness and progress that they envisioned" for this era of personal computing.
