Artists you didn't get first time around

I guess some of my favourite artists now like Placebo, Depeche Mode and Bjork I didn't really appreciate in my younger years. I liked the most prominent songs by Pet Shop Boys, Portishead (Glory Box) and Massive Attack (Teardrop, Unfinished Sympathy) but didn't bother checking out any more of the back catalogue by these artists... but my god I'm glad I did, totally astonishing.
