When I listen to some odd time signature songs I have some serious trouble dissecting the time signatures at times. Songs with 6/8 or 3/4 are easy enough to identify, but some progressive rock/metal songs make it hard on me. I'll usually get caught up with a riff or the singer's timing relative to the actual song time signature. Are there any methods for counting that will help me figure out the actual time signature of the song?
Tool - The Pot: I think this one is 6/8 with an occasional 2/4 bar. I heard it on the radio earlier and it made me think of this question. Not a huge Tool fan, but they do some interesting things.
Opeth - Coil: I'm specifically interested in this one. I cannot for the life of me figure out the time signature. It could be that I'm being deceived by the riff/musicianship of the song itself.
