Well Filth the only answer I can give is that I'm don't really consider going to see a DJ the same as going to see a band. I can have a great or bad time at both. They both involve music.
Good DJs aren't really just putting a CD in and hitting play though.
Daft Punk live is really close to just hitting play on a CD though I will say. I can say the same of the band Tool though. If you want to experience a Tool concert just turn your stereo to max, turn off all the lights except for maybe some lazers or wierd backlighting and enjoy. They sound fantastic but it's not like they are jamming or improving.
Now a good jam band, thats where I'm in the zone for live music. Something completely different even when the playlists could have been the same or close to it between two shows.
