Squeezebox Touch not diplaying some music files


Hi,
I am hoping someone can help me with this dilemma. I have been using a Squeezebox Touch to wirelessly stream music from my itunes library (via Logitech Media Server), with excellent results. I have had no problems with my entire music library showing up on the Squeezebox touch. All my music has been converted to high quality AIFF files. Somewhere with the last 1-2 updates on the Squeezebox Touch and itunes, I have lost about 5% of the songs on my library. That means that those songs do not show up on the Squeezebox Touch but I can find them if I use the Search function. This is a major annoyance as I have to try & remember which songs I am missing. None of the songs have any restriction such as DRM.
Could any of the experts in Computer audio shed some light on what might be going on and what can be done to fix this problem? I would be very grateful.
Thank you!

it once happened to me and it happened to be missing file extensions (.mp3) that amazon forgot to append for a few days.
Thank you to everyone for their valuable suggestions. Much appreciated! I will attempt the fix tomorrow and get back with an update.
This suggestion might be of some help. It restores the iTunes library to an earlier state, and is described as often being a solution for, among other things, library corruption that may result from "upgrades."

It's very simple to do, and very simple to undo if necessary.

I have 3612 CD's ripped in loss-less, with 42256 songs occupying 1.2 Terabytes of space. That 2972.5 hours of playing time or almost 124 days before hearing a repeat. LMS has no problem indexing it. My last scan took exactly 100 seconds.

Seams to me that it probably comes down to 3 possibilities:

1. Corrupted index file

2. iTunes has changed something with tagging/file type for the missing songs. Is the latest MP3 Squabbler installed in LMS?

3. Change in the way LMS is indexing the iTunes library.

Keep us posted.
"My suggestion is if rescanning his library doesn't work in Logitech Media Server, then try adding/importing library into iTunes AGAIN. Basically delete old state info and re-add."

I don't know if we're talking about the same thing. I haven't used iTunes in years, but if I remember correctly, it would sometimes change tagging info and file structure on music I added to the iTunes library. If there was a way to stop it, I couldn't find it, so I just stopped using iTunes altogether.

Something else I just thought of is that I've used several media players that couldn't handle large collections. I never tried LMS, but it may be something to consider.

"If that doesn't work, try adding the library to iTunes so it will rebuild tagging info. Usually I delete everything in iTunes folder before adding the library."

That's exactly the problem I had with iTunes. It takes matters into its own hands, and starts retagging everything. I don't see why you would want it to do something like that.

He configured LMS to use iTunes ... I never had problems with iTunes or LMS. BTW I prefer LMS over JRiver, PS Audio, MinimServer ... for SQ and reliability. Too bad they got bought out.

My guess is index needs updating in LMS.

Have you tried rescanning your music in Logitech Media Server Control Panel? You can look for new music or rescan the entire library.

If that doesn't work, try adding the library to iTunes so it will rebuild tagging info. Usually I delete everything in iTunes folder before adding the library.
Have you re-scanned your library in Logitech Media Server? You might want to delete the old scan file and start from scratch. Also, make sure iTunes music files are all in one directory.

Might also want to check the setting for how albums are sorted/scanned.
Hi Zd542,

Your detailed reply is much appreciated! I will start working on this.
Many thanks!
Tags are labels you assign to music files to make them easier to work with. Things like genera, title, artist and year... etc, are some examples of popular tags. It sounds simple, but you need to be careful. Its easy to confuse tags with the info you see in your file manager. When you are looking at tags, its usually called library view. When you are looking at music files in your file manager, its not the same thing. For example, if you are in iTunes listening to music by The Rolling Stones, the tag for the artist is The Rolling Stones. Now, if you leave iTunes and access the music files directly, the artist could be Rolling Stones instead of The Rolling Stones, like you see in iTunes. Tags and file info have nothing to do with each other. They can be different. I bring this up because it can drive you crazy if you don't understand what's going on. Someone will change or edit tags in a program like iTunes but when they look in their file manager, nothing has changed, and they think something is wrong.

In your case, I think its very likely, iTunes changed some tagging info, file info or both. Using The rolling Stones as an example again, in iTunes, you may have tagged "The Rolling Stones". If iTunes re tagged some of your music using the name Rolling Stones instead, its now a different band in iTunes. And that's how you loose your music. In this example, you would fix things by changing the tag Rolling Stones to The Rolling stones. Once the tags are labeled properly, your music should show up.

If you need good tagging software, download a free music player called Quod Libet. Since you didn't say what OS you have I chose Quod Libet because it works on Mac, PC and Linux.
Hi Zd542,
Thank you for your reply. I do know that I can find the songs on Squeezebox Touch but I have to use the Search function, which means that I have to remember what I am looking for. Pardon my ignorance but how do I re-tag the music files? If I can do it, that might fix my problem.
Thank you!
I think the problem may be with iTunes. I don't think you actually lost anything, it was probably just re tagged. I had problems with iTunes in that it just took over and tagged my music without giving me an option. I don't know if there's a solution, I just stopped using iTunes. To check, look at your music collection with a file manager. If everything is there, all you need to do is re tag the files.
