The Notorious B.I.G. isn't going anywhere, anytime soon. Tupac may put out posthumous album after posthumous album, but B.I.G.'s rhymes apparently live forever, and ever, and ever. Nowhere is there better evidence of this than in the mashups produced with his tracks mashed into them in it year after year. The latest batch aren't too new, but they are nothing short of stellar, and we've rounded them up: teen popster Miley Cyrus gets her party on, epic post-punk/R & B revivalists The xx go "Runnin" with B.I.G. and 'Pac, MGMT gets their electric felt, and Passion Pit goes toe to toe with Biggie Smalls and Beyoncé Knowles.

The best of the new class has got to be the Miley Cyrus vs. The Notorious B.I.G.'s "Party in the B.I.G." Not being a Miley Cyrus fan at all, it's hard to admit that smiles were cracked at this piece of brilliance -- Miley's "Party in the U.S.A." blended with Biggie's "Party and Bullshit" -- thrown together by pro skier Andrew Hathaway, clearly going crazy in the off-season. But this insta-classic's a fun, ridiculous banger, perfect to be tossed on during your next party right as it hits its peak. The official mix was pulled from Hathaway's downloading spot, but we think you might be able to find it on YouTube (below) or downloadable here.

The next must-download comes by way of a DJ set who go by Quix vs. Elliot; they threw together the hottest of Pitchfork's 2009's Best New Music class, indie post-punk dream pop youngsters The xx, alongside Biggie and Tupac. The original track comes from the soundtrack to the documentary Tupac: Resurrection, and it's a track with soundclips and rhymes from the long gone formal rap rivals, diced up and spread out on The xx's "Intro" track, which really is the first track on their album (and what some people would call their favorite, despite being only a barely-two minute instrumental; they're that good). You can download it here, and listen to it below.

The other two you might want to check out: ddpesh's remix of the Justice reworking of MGMT's "Electric Feel" with B.I.G's "Nasty Girl." It's nothing completely surprising -- at this point, nothing mixed with Justice or MGMT is surprising -- but it's still, like the Miley track, a decent party jam, and some decent work went into it to make sure it flows well.

The final entry is, admittedly, a bit much: B.I.G, Passion Pit, and Beyoncé. The relatively well known Xaphoon Jones, who produces for up-and-coming indie Philly rap group Chiddy Bang, has thrown Passion Pit together before (with Major Lazer, no less) to great effect. And it shouldn't surprise anyone that Passion Pit makes for incredible remixing material, regardless. But with the extra topping of Beyoncé’s "Single Ladies" sample, it proves wrong the adage that there can never be too much of a good thing. In this case, there can be, and there was.

That doesn't make it any less awesome for what it is, though: someone trying to take something old and teach it a new trick. And if Girl Talk can throw 100 samples in a song and make us listen, isn't the greater challenge to do it with one, two, maybe three at the most, and sustain our attention for a full track? Here's to hoping there's more where this came from. Besides, anything that can draw out Biggie's legacy isn't the worst thing that can happen to music, you know?
