It's actually the artists who can sue since it's their work being distributed. The distributor might have a fair use argument since the purpose is artistic preservation and the artists clearly never intended to profit off the songs. If a trendy DJ remixed one and it saw commercial success, the original artist might have a case.
The fact that their music was originally distributed uncontrollably and for free within keygens and cracks probably means that the artists don't care about sites like this.
