Good Method to improve listening comprehension?

[johngxx]

Hey, I am a Spanish learner from Finland and I would like to know if somebody know a good method to improve listening comprehesion, I have the problem that I found either very advanced podcast or very simple ones and not many guide you on how to listen, I tried the most common ones when I type SPanish podcasts or audios at Google but after trying I've found that they don't help me out to overcome my struggle listening movies or native speakers. Thanks in advance folks.
