Your build looks pretty good to me.
My points/things to consider:
Do you need more than 1TB of space? A 2 or 3TB HDD, or even larger, wouldn't be too expensive and would give you a considerable amount of additional slower storage.
I've never been a fan of MSI for video cards - I would consider Asus, EVGA, or maybe Zotac, all are similar in terms of pricing.
Your PSU is overkill unless you plan on adding a lot of stuff down the line, these days even a quality 550W would power your system with headroom. Nothing wrong with a better than necessary PSU but you could save a little cash.
If you're planning on overclocking at all, I would consider a better than stock cooler, I'd also consider this if you wanted a quieter system (although the Intel stock cooler won't be terrible in that respect anyway). If you're not planning to overclock you might also be able to save a little by going with the 4790 (non K edition). For coolers, have a look at the Be Quiet Dark Rock, Thermalright Archon, Thermalright Macho for starters.
If you're recording music, I would consider a dedicated sound card. I don't pretend to be a pro in this area and perhaps you already have equipment you're going to be using for this, but I thought I'd mention it. Something like an Asus Xonar DSX would suit general usage, I'm pleased with mine, but might not be much good for professional audio usage, I don't know.
If you wanted to take a different tack, you could also consider an Intel X99 based system with a hex core CPU - your budget allows for this and this should be better for rendering and other heavily multithreaded tasks even if it won't perform much better in gaming.
