>So 'cos the song in question takes a while to get going, that gives you right to download it without permission and without paying for it?
Woah, laddie. That's a mighty big straw man you're building there. I know 5th November is around the corner but you're getting rather carried away here. I only said 30 second previews didn't allow for decent representations of songs. At no point did I advocate copyright infringements as an alternative.
> Notice you picked on prog bands, who are notorious for making 25 min epics, to make a convenient argument there!
Firstly, prog bands? _bands_? fun. aren't progressive rock. More like power pop.
Secondly, you say convenient argument, I say picking the most obvious examples to make a point without wanting to spend all day thinking of examples. My point remains valid nonetheless but to assure you that 30 seconds isn't enough to make a good judgment of a song here are further examples, this time covering the genres R&B, Dance, Drum and Bass, and Classical:
"Graduation Day" - Kayne West
"Right here, Right now" - Fat Boy Slim
"Slam" - Pendulum
"The Planets Op.32 Mars, the Bringer of War" - Gustav Holst
The Kayne West track is an example of a song that starts with a monologue and breaks out into a song. Fat Boy Slim and Holst are examples of songs that build to a climax. While the Pendulum song is an example of a song with monologue and change of style from rap backing track to trance.
