You wrote me by personal message, that Mp3tag displays for the music files the information about Tag-Read (Tag-Types) having the value "ID3v2.3 (ID3v1 ID3v2.3)".
But this information does not say anything about the ability of the player to understand both Tag-Types and to use the Tag-Type ID3v2.3, maybe it can handle only Tag-Type ID3v1.
There is an open task up to you, which has been not answered yet.
Getting all Songs in an "ALBUM"
It is still not clear what Tag-Type is supported by the LG Rumor Touch.
Please find it out.
I am rather confident, that a concrete answer will let us help you, to find out what is going on with the player's logic.
