dear Darkstar, you asked,
"why would anyone in their right mind pay $.99 for a loop when they can buy a full track for $1.50 and cut out countless loops for 0 dollars?"

It's all about consent. When you buy a full track for $1.50 and use countless loops you are, in effect, ripping off the artist
without their consent.
When you buy a loop for 99 cents the person selling it to you is giving you consent to use it.

In the case of this particular site, they are giving away a lot of free samples.........I'm assuming that you aren't compelled to buy anything
to get them.

so it's like dishwashing soap, if you think that the samples are cheezy , simply don't buy them. It doesn't mean that the people who are trying to sell them are bad people, for chrissake, any more than the person who's selling their MP3 for 99 cents on ITunes is a bad person for trying to get people to buy what they are selling.

Personally, I tend to make my own loops because I think it's more creative and unique to do so.

but one person's cheese is another persons' masterpiece.

I'd suggest that you take all this vitriol and put it into making your own music.
