^^Those are nice! I actually like the first one a lot! I want some music posters too, but it's really hard to find some when you're not into Gaga and 50 Cent!
For smaller pictures I use
Scotch Double Sided Tape because it's very easy to remove from both the wall and the poster. For bigger ones I used to have the ones by
Tesa. They were awful, too. I spent hours blow drying my walls trying to get it off when I moved
Posters were all torn as well.
Now I prefer getting all my posters framed. Of course there will be holes but I think painting over them is less annoying than trying to remove the stickers. Plus, I find that posters fall off whenever there is a change in temperatures when you use stickers and I hate that and that doesn't happen when you hang them up or use tacks.
