It seems the world of rap and mixes with video game music are becoming more and more popular these days, and for good reason too. They blend so well! 2 Mello is a rapper known for this sort of thing, first with Chrono Jigga, and now with Castlevania, or rather Nastlevania in this particular case.
In his new second album storyline, Nas is a Belmont by blood, and has been summoned to fight through Dracula's castle to defeat him, restoring good music and light to the world. 2 Mello's new album is also free to download, with each song being selectable individually if you like, (donations accepted).
Here are the track listings.
Personally I recommend "Made you Wicked" and "One Night", which are mixtures of the original Castlevania and Symphony of the Night game music. 2 Mellow also indicated he plans to make this story into a trilogy mashup. He also expressed an interest in the music from Smash Bros. on Twitter recently, an interesting prospect if he makes that happen. If you want to check out the whole album, which I highly recommend, you can do so here, or below right "here".
