I am restoring my system to install Yosemite. I've had the same iTunes library for years and it has suffered some corruption/glitch. Every time iTunes is launched it must "Analyze Gapless Playback." I can fix this by dragging the 4 library files to the trash and starting fresh with just my music, but then I loose my ratings and play count. Is there a way I can quickly restore my play count without having to sit their tediously and click through each song?
