An anonymous Apple insider has tipped off the Unofficial Apple Weblog that he believes the corrupted iTunes libraries they have been seeing recently are caused by a conflict between iTunes 7.1 and LimeWire.
The email reads:
I work at [an Apple service provider]. Today we saw [multiple] iTunes libraries completely corrupted; looks like the culprit was Limewire not playing well with the newest version of iTunes.
All had just updated to the new version of iTunes and all had Limewire set to automatically update their iTunes library with new songs. One [library] was not salvageable, though the other two were (after much pain and suffering).
It’s believed the tip is related to the Mac versions of the software. The situation on Windows versions is unclear.
TUAW points to two threads on the Apple support forum as a starting point for concerned users 1 2
LimeWire users with difficulties can find support on the Gnutella forum.
According to a recent NPD Group report, Limewire users took a 62 percent share of p2p music downloads in 2006, with the average user downloading 309 tracks.
