I appreciate that this thread is not concerned with the aspect of copyright, but I'm with @Devalish on this.
In the UK it's ?9.99 for a Premium account. That's all the music you want on your computer or mobile device, plus you can download it so that you can listen to it offline (as long as you use the Spotify software). That means I can listen to it on my PC, on my
iPhone and also through my car's bluetooth stereo.
If you're so poor you can't afford ?9.99 a month then you're presumably also too stupid to be able to either break Spotify encryption and / or too dumb to follow instructions from someone that has managed to do it. Back away from the Internet ...
Piracy sucks. The film companies are suffering because they are (currently) failing to embrace new technology and given that you can download a 1080p film as fast as your internet connection will let you from pirate sites, versus paying for films that take an age to come out and only allow 720p quality they're surely going to continue to suffer. Therefore, for the moment I hope they continue to suffer until they realise they need to raise their game and stop ripping consumers off.
Spotify has corrected this problem within the music industry and provided a quality product, with a quality catalogue at a fair price. I don't think that there is any excuse to pirate music any more. You're just a thief against that backdrop ... unless you can find a decent reason to justify trying to (and amusingly failing) to steal music from Spotify?
The only thing that I can think of (and it's WEAK argument) is that you don't like their music player.
