Hi TT2,
I understand what you've written, however, it's not only songs purchased from iTunes and that disappered Iand therefore could be re-downloaded from the cloud), but many songs uploaded from my own CD collection also disappered. Moreover, there's no way I accidentally deleted these songs myself: this happened to well over a thousand songs, and all I did was sync my iPhone as usual.
On your iPhone > Summary tab when connected to iTunes do you have the option Convert higher bitrate songs to... selected?
Are you syncing via a cable or over the air?
Syncing copies tracks from iTunes to the device, but in general not the other way. If you'd noticed problems with the library then you should not have synced until they had been resolved. It might have been possible to recover the missing media from the device.
The WAY they disappeared from the iphone is also strange. One of two things would happen: 1) a song would look fine until I clicked on it. Then it would immediately disappear - literally disappear from the phone screen. When I searched for it, the search would come up blank. 2) Same thing, but it would reappear grayed out and unplayable.
There are a number of phases to the syncing process. If it is interrupted it is possible for the device to have an entry for a track which isn't actually present. Normally at this point I'd be suggesting you backup and then immediately restore the device to resolve that issue, but first you're going to want to rebuild your library.
Then there is the movie problem I described above. Again, these were home videos I had uploaded myself; they were NOT purchased from iTunes. Most stayed there, but were unplayable. Others disappeared. There was no logic to it at all.
Unplayable in iTunes, or on the device? If the media is in iTunes it can be sorted out later. If it has gone missing from there too, and you have no backup, then we're back to the long shot of file recovery software.
I want to emphasize that this happened WITHOUT UPDATING ANYTHING. I'm still running 10.8.5 on my MacBook Air, and 7.0.3 on my phone. I am not an early adopter of updates - precisely because I want to see if others experience any problems. I certainly did not expect to have problems suddenly appear without my changing anything. How could this happen?
i don't know, but sometimes software behaves unexpectedly, and disk drives will fail without warning. A solid backup strategy is your only defense against the inevitable.
This morning I synced my iPhone again. (Again, I did not update anything; I just synced.) iTunes took some time, and replaced over 1100 songs and movies on my iPhone.
Syncing should resolve any inconsistencies between the device's index and its media folder. If the iTunes library has been reconstructed in some fashion (which can happen occasionally happen automatically following a crash) then it may also replace tracks that are already on the device. In iTunes each track is represented by a unique ID and when syncing the list of IDs in the library and on the device are compared with each other to work out what needs to be synced, and to transfer ratings, play counts etc.
So far it seems fine. But I still want an explanation of why this happened. And judging from everything I've read here, I'm certainly not going to do any updates on either the phone or computer. I'm going to wait until this is sorted out.
Sorry, I don't have any explanation. Golden rule is to backup before updating, and restore from backup when something goes wrong. Whatever the underlying reason for your data loss it cannot be repaired by an update to iTunes. Even assuming a problem with iTunes is the cause it is unlikely to be "sorted out" unless it is properly identified, the circumstances that trigger it can be reliably reproduced, and enough people submit cogent feedback/bug reports. Generally best to keep up to date so that at least known bugs have been addressed.
