I'll write small reviews of the releases I tried from this list here and add stuff to it whenever I listen to more.
ESNO - Visionary: Really blew me away. Great electronics, great mixing and really relaxing. This would do really well as studying music too. I'd recommend everyone to try this, because it's simply beautiful in its own way.
FilFla - Fliptap: A pretty good release. It didn't grab my attention well enough for me to keep it on my mp3-player, but definitely not bad. It shouldn't have been any longer than it is as well, I noticed that I'd get bored easily at the longer tracks.
M-Koda - Inga: Incredibly surprised at this one as well. I thought this might bore me after a few tracks, but I was completely wrong. Definitely recommended.
nego - SANSARA: Absolutely great, nego is great at what they do and this album shows it. Each instrument is crucial to the compositions, which also means that using low quality gear to listen to this completely ruins the experience. Each instrument does its job wonderfully and even my friend who isn't that big on electro-rock enjoyed this record a lot.
fresh! - What Are You Doing In This Confusion?:
Jimanica - Torso: Even though the electronics were well done and created nice beats here and there, I couldn't get over the incredibly annoying distorting vocals. They completely ruined the atmosphere in most of the songs for me, which left me really unimpressed around halfway in. I was practically waiting for this to be over at a certain point. If you can stand distorting vocals, it's probably a great album though.
LAGITAGIDA - CartaMarina: This sounds like an instrumental heavier version of school food punishment and I'm actually loving it. All five tracks were just nuts and really well composed. Let's just say "short but sweet". I will definitely keep an eye on these guys!
TK from 凛として時雨 - flowering: Good album. I was afraid I wouldn't like it too much because I'm not a big fan of TK's voice but he didn't overdo it on his this album. The upbeat tracks are all very diverse and actually pretty damn great, my only complaint would be the mash-up of ballads at the end, it kind of got boring because of that. The ballads didn't sound very different from eachother most of the time, which is a shame. Overall still very likeable.
アルカラ - ドラマ: This has to be the best アルカラ release I've heard thus far. The tracks are diverse, have interesting hooks and bring new things to the table that I haven't heard before on other アルカラ releases. Even if you're not a big fan of indie music, I'd definitely recommend this EP.
トクマルシューゴ - In Focus?: Great album, never thought I'd love this style of music as much as I did. Though he's not the best vocalist, his vocals really match the playful atmosphere of his compositions. Best listened to on fine spring days.
