Summary0012806: iOS8: In some cases audio doesn't match title on iPhone
DescriptionThere were several reports that iPhone can get to state when titles on the device doesn't match the actual audio content.

I haven't been able to replicate, but found that it can happen in case of an unexpected iPhone reboot ( 0012774 ), the reason is explained in 0012750 , the iTunesCDB cannot be uploaded because of the reboot and after the device/MM restart MM thinks that the already synced files doesn't exist on device. Thus it generates filenames like /iTunes_Control/Music/F01/_Mas.mp3 that might been already used for another file in the previous sync (that exists on the device, but MM thinks it does not).

To simulate the issue:
1) Sync one Album1 from Artist1
2) Run iFunBox and manually delete the /iTunes_Control/iTunes/iTunesCDB file
3) Sync Album2 from Artist1
=> the content is mixed

The solution should be 0012750 that was finally reverted, another solution is 0012266 that has also some cons as described here 0012266:0041251
TagsNo tags attached.
Fixed in build1752

I used solution similar to 0012750, now the content should be always in sync, because iTunesCDB is uploaded after each successful "Air Sync" commit batch.
