[LG V30 Questions & Answers] spexwood:
I have 2 potential solutions for you to try, depending on whether you're using a MAC or PC. I see you're posting from an iPad, so there's like a 33% chance you have a MAC, 33% chance of having a PC, and 33% chance of having no computer at all.

First, you NEED a computer of some type (MAC or PC) in order to do any of this. Your music needs to be on the computer too. If you have a computer, but store your music only on your phone, then you'll need to copy everything (or at least the files giving you issues) to your computer.

ALTERNATIVELY, you can take out your SD card and insert it into your computer. You just can't use plug your V30 into the computer and have any of this work. It's because of Android using MTP, so it must be one of these options.

PC:

IMPORTANT: Before doing anything, go to where your music is kept, select all folders or files. Right click and select properties. Make sure "Read Only (only applies to files in folder)" has no check or square in the checkbox. Click the box until it is clear. Click OK when done and let Windows change everything.

This will make sure that you can edit the file info of your music files.

Download MediaMonkey from http://www.mediamonkey.com/download/

The free version will do everything you'll need

Install MediaMonkey. Upon first startup, it'll ask you to choose your music folders (where you store your MP3's on your computer).

Once all music has been imported, choose a file giving you issues, right click it, and choose Properties.

Go to Artwork tab

Now you have 2 options:

1) Click ADD and manually select the album cover image from your computer.

or

2) Click the little icon to the left of ADD to have the program find the album cover from the internet based on the file properties (artist, album name, track, etc).

(NOTE: to delete an image, click it and press the actual delete key. It took me a while to figure out)

No matter which route you choose, you will then be brought to a window where you can label the artwork type and some other options.

Choose the image type based on your preference.

IMPORTANT: Here is where the potential solution comes into play. For "Image Location," you need to choose, "Save image to tag (if possible) otherwise save to file folder."

This will attempt to embed the artwork into the actual file properties, where other info like artist name, album title, etc is stored on the MP3/FLAC file. If it can't do it (such as the file being read only), it will instead save the image file to the folder where the music file is stored. You want the artwork to be embedded into the file itself.

Click OK on the Add Image window

At this point, you can edit any other info in the other tabs in the File Properties window. Before clicking OK though, I'd recommend checking the "Apply to all files in the album/series" checkbox. Otherwise, the album artwork will only be applied to the file you selected. If checked, it will be applied to every file with the same album tag. TIME SAVER

Click OK when done and HOPEFULLY your problem will be fixed on your phone!

MAC:

Open iTunes

Right click the file and choose "Song Info"

Go to Artwork tab

Click the Add Artwork button and find the artwork file on your computer. Unlike the PC steps, you can't have the program automatically find the file from the internet. :(

Click OK when done.

Yeah... the MAC option is so much shorter than the PC option. LMAO

I REALLY hope this helps! Please let me know what happens and contact me if you have questions or problems.
