I love Frontiers.. I think that outside of Frontiers, Escape, and AOR Heaven, I barely buy anything else these days.
That said, their releases end to have little staying power - usually after a week or so, they go off of rotation and never come back..
I then get really excited for the next releases - wash, rinse, repeat
I wish Frontiers would have a subscription program where you could buy all of their releases for the year (mp3 would be fine for me) - I'd be happy to pay up in advance..
