Problems trying to WILD (orly?)

Hey everyone :)
I've been lurking around for a while now, but just now decided to post some problems I'm having when trying to WILD with hopes that some of you can help me :)
I have this problem, where I take too long to fall asleep normally for some reason, and I rarely fall back asleep when trying to WILD with WBTB, and when I do it takes a LONG time. Here's my problem though, when I try WILDing I get to see some HI (some dark purple, blue or red sometimes blurs, just abstract stuff) but that's about it. I never get past that. Usually I spend about 30 minutes laying down motionless (besides some twitching), but more than once I have spent more than 1 hour motionless (counting from 1 to 300 VERY slowly) only to stop at HI.
I just have a few questions that would help me a lot if someone answered for me :)

1) Can I listen to music while trying to WILD? I don't mind staying 1 hour motionless, but I'd prefer it a lot if I could listen to Radiohead while doing it :P

2) Am I supposed to change positions after some time? I read somewhere (either here or ld4all) that you should after a while because your body checks it or something...

3) Am I not doing something I'm supposed to?

4) Would it help if I started practicing meditation?

Anyways, thanks in advance and sorry if I wasn't very clear, my first language unfortunately isn't English :)

I've never been able to WILD, but I know how it's done (kind of).
1) Maybe. This one really varies between people.
2) No, unless you think you're in a lucid dream.
3) N/A
4) Maybe. I think meditation helps with recall and lucidity.
Sorry if this isn't too much help.

Thanks for answering those questions :)
Well, I've tried WILD and CANWILD loads of times, but they never work, and the only lucids I had (only three) so far were all DILD, so I think I'm going to try and improve that, or maybe try other techniques :)
