Well I'm new to pandora but I want to save space on my iPod so I'm using that now and I was wondering if instead of listening to certain artists chanels are there any channels that have a mix of artists of the same genre also if there are what channels do u recommend for me if I like rap but nothing to hard but music like wiz khalifa eminem lil Wayne but nothing harder than that also I would need another channel that has any kind of 80s rock such as aerosmith
