I'm looking for the singles of the OP and ED songs of Yu-Gi-Oh!, GX, 5D's and Zexal, but I'm having a hard time finding them. Especially singles for the first two series in decent quality. Can someone point me in the right direction, or upload the singles for me? As in, the entire single (most of the time with instrumental tracks and stuff)

Here's a list of all OP/ED songs. Usually Google is my friend, but this time... I can't seem to find them.
