Groovy
Like the EFX on the beginning organ, flanger/cutoff, its smooth, the drums are crisp, seems like good progression, the bass is fitting and not overpowering, the second organ ties in with with the first, good melody, the break with (what sounds like) a guitar with some FX is a little unfitting to me, But what you bring in right after it makes up for it, The guitar comes back, but it ties in with the little travelling synth you have in the background, From here it pretty much repeats with variance within itself from 3:30 onwards, The ending is nothing amazing neither bad in any way, It is still loopable.
If there was anything to change it would be some very minor FX tweaks and drumwork, but it is great as is.
