I don't usually spend much time on mash-ups--rarely for me do they exceed the pleasure of listening to the original songs. Sometimes, though, even if they can't do that, they succeed in reawakening your love for the originals and cluing you in to aspects you never fully paid attention to before.
(Thanks to Alex for the tip!)
Just when I thought I was losing interest in "Poker Face," here comes DJ King Rollo with a mash-up of Charlotte Perrelli's "Hero" and Lady GaGa's "Poker Face," re-entitled "Hero Face." Taking the instrumental from "Hero" and the vocals from "Poker Face," the end result is a-mah-mah-mazing. It's really well done and, if nothing else, should increase your appreciation for just how killer (and beautiful) Fredrik Kempe and Bobby Ljunggren's writing and Bassflow's production are, as well as maybe get you thinking that the toplines Lady GaGa co-writes could work outside the RedOne context. Though I'm sure she'll never go in this direction, "Hero"'s combination of this style of electronic beats, longing strings, and piano all creating a poppy song is something that has a substance to it that I don't think even I--who loves "Hero"--fully appreciated until hearing this mash-up. As much as "Hero" got written off as a cheap Europop rip-off of "Cara Mia" in some quarters (not here!), if anything, this mash-up proves to me just how international in quality the work that went into it is.
In short: probably the best song I've heard this week (edit: though the chorus of Girls Aloud's "It's Your Dynamite" is really good).
