UNKNOWN TITLES OF SONGS

If your ripping software does not automatically pull the song titles from the Internet, you must type the entries in yourself. This does not happen automatically.

incompatible music format?

1. Click on "Advanced" which is found at the top of the screen. Select "Get Album Artwork" from the drop down menu. It will ask you "Are you sure you want to get album artwork?" Hit "Get Album Artwork". Before you do that, you can select "Don't ask me again" if you don't want this to pop up in the future.
2. Wait until it is done searching for the artwork. A window will pop up saying that it either found all artwork or they didn't. If they did, then great, your done, plug in your iPod and start jamming. But if they didn't, you can still jam away, but check the song title, album name, artist, and genre to see if you got it typed in correctly. Type in what they are supposed to be and try again.
3. If they still can't find it, then you can add them manually. Look at the link below to find out how to do it manually.

OR
If Itunes wont find the art work:

1. Find the artwork for the album on the internet. Try using Wikipedia. Click on the artwork to get a larger image. If you can't find it there, I'm sure you can find it using Google images. Anyway, once you find it drag it to your desktop. Make sure it is on there before you continue.
2. Next, you need to highlight the songs that are in the album you are getting artwork for. To highlight multiple songs, click on the first song and then while holding the shift key click on the last song. To highlight multiple songs that aren't grouped together, click on all the songs while holding the command key on a Mac and ctrl key on a PC.
3. Now go to "File" then "Get Info". A window will pop up asking you if you want to edit multiple items. Click "Yes". Another window will pop up labeled "Multiple Item Information". You will notice a box on the right hand side of the window that says "Artwork". Click and drag the artwork that is on your desktop into that box. It should appear there. When it does, select "Ok".
4. When it is done processing, plug your iPod into the computer, sync it, and take your iPod out to start listening to your improved music.

I clearly understand your problem.....the best way to sort it would be to create a new music folder...put all album folders separately in this new folder....rename songs in the respective albums folder and then sync this folder to your player....try with a couple of songs first...if it works you can change your entire library as mentioned above....a difficult job...but helps manage your music better..:)

on the left hand side above the word create playlist, you'll see an eighth note next to the word music. click on the arrow next to the word music.click sansa c140 (if u have one) then click the arrow nest to sansa c140 and click on folder. then open it and you'll see a picture that looks like a stack of cds. click on it ONCE then press the delete key. it will delete allyour songs. then go back to the library and download back the songs you want.

right you need to convert the image you want for your album art to a thumbnail and put it in the folder where the music is

software image to thumbnail: http://www.fookes.com/ezthumbs/

try doing it via click and drag to the players music folder , works for me 

you need to make shure does songs end in .mp3 with lowercase letters for the song title its just a encryption problem!

rename all the songs after download from the net then put them in the mp3 player ! its not recognising the letters from the original persone who wrote the titles

Sometimes all you need to do for that is profile the songs. This organizes the songs into the correct catagories.

I assume this is in a PC? Simply right click each title whilst in the PC and click on 'Rename' Or click file/save as/and give the file a name This incidently will leave an un-named copy on the computer
