Decent 64gb micro sd card?

[King Oriax]

This seems like the best forum for this so eyy. I'm looking for a cheap 64gb micro sd card for my phone, majority of it will be music and some will be movies so It doesn't need crazy fast speeds or anything. I bought this for $10  http://amzn.to/1FVHuix butafter 8gb of anything was put on it started corrupting so i'm assuming the $10 card isn't the best plan. Some of the music files are 320kbps (higher quality) so It can't be dirt slow but I don't really know how sd card speeds work other than higher numbers are better. I don't want to spend over $30 and there are a few dozen options on amazon so I figured I'd ask here to see if anyone had one that they felt was superior. I was going to get this one but figured I might as well ask first http://amzn.to/1dTTEgY
