Custom Track Problem

[gameroftheuk]

Don't ask me if I converted it correctly with EAC PSP Edition and renamed toc to gta, don't ask me if I setting up the folders correctly in the ms cuz i did it correctly and some songs will play while others don't. The custom tracks I have that worked include: 99 Red Balloons - Goldfinger, Africa - Toto, Sister Christian - Night Ranger, Video Killed the Radio Star - The Bugles, Turn Up The Radio - Autograph. But the following two songs will not play: Broken Wings - Mister Mister, Out of Touch - Hall & Oates. when these songs are selected while in a car, the title will appear then nothing was playing and I try to select the next track but it won't do and I have to go to the menu and turn custom tracks off and on. Do u know what the problems are?
