Funny you bring this up as I just listened to the new Crazy Lixx tonight and the last tune is a 7 minute plus tune. And I was thinking about about 5 minutes....This song needs to be over lol.

There's another song on it called Caught Between The Rock N Roll. It's a cool tune but it drags out to about 4:40 long and the last 45-60 seconds are basically just a waste. It would've been much better as a 3:45 song as it would've been easy to trim it.

So yeah, definitely think songs can be too long. I think somewhere in the 3-4 minute range is basically ideal for me. Any shorter, it feels to short. And any longer, it seems to start dragging on and starts feeling a bit self indulgent or something.

I know there are some longer tunes I do like so I guess it's not a hard and fast rule. I think there has to be some cool instrumental type stuff going on in the middle though to make it work.
