I believe Reanimation felt more cohesive because it involved a lot more input from the entire band. Not just some remixers emailing Mike (I'm assuming) some remixes they made from the stems, and Mike remixing a couple songs and recording a couple verses. Reanimation felt almost like another studio album with the way they completely rebuilt those songs in every way, while Recharged just feels like a thrown together compilation of EDM remixes. Don't get me wrong, I'm just speaking from my own personal opinion. While I like both albums, I don't really think this should be compared to Reanimation. They are both technically remix albums, but the vibe and experience are completely different to me.
Overall, the remixes are actually pretty cool. I do think Recharged has some replay value, I only really dislike the middle few songs (literally #6-9), but Reanimation to me was and is way more special. I really feel like the band (all 6 members) put a huge amount of effort into Reanimation, and it doesn't exactly feel that way with Recharged. Probably they all just listened the tracks to choose from and they voted on which to use. As in "yeah, put that one on there". Am I wrong, or was Mike the only person in the band who actually put new studio work in to the album (with his remixes and verses)? That question not including ALTNC, which (I could be wrong) was just Mike & Chester actually recording, with input from the rest of LP.
As far as Mike doing another FM album or EP, I think it'll happen. Given the mention by Ryu on the IBG remix, it's at least something they're "considering" (no pun intended). I think that if it happens, it will be in 2015 or 2016, after the next LP album release and initial tour that will come with it. I would love it if it was sooner, Mike has shown he definitely hasn't lost it. His verse on the STB remix is one of my favorites from him ever, LP/FM/anything else. I just think Mike is focused on Linkin Park for the immediate future, and won't want to spend time on another project right now.
