Remember to the fact that is just my opinion.
I like to make my own loops using Fruity Loops 9.
Its not hard to make good music with all the plug-ins they offer.
Try something that would be beneficial to a build. Like the defaults played a roll for jungles, icy places and whatever else.
Just that full songs looped don't make sense in blockland if you can simply listen to the whole thing using something else in the background.
