I don't think Continuum will be up on Limewire. It'll just be the tracks from the Hotel Cafe shows but given the album title Continuum. Idiots rename things all the time on Limewire, which is also a bit useless for album downloading. If you want album downloads in a program like that i'd go for Soulseek. Bittorrent and IRC for the win overall though.
Also, even if you have intentions of buying the cd and you download it, alot of people 'yeh great why not, you've bought it too'. The studio's eyes 'you stole it by downloading it off the net.' Technically still illegal downloading even if you've bought it or not basically.
