I'm a fan of HSS! and would recommend any of their songs. It's great having music videos like this in VR and I would love to see more artists/groups utilizing the medium. The songs might only be a few minutes of content each but I rewatch them a lot. I find music videos are a good way to wind down after playing a VR game but before taking off the headset.

All of their songs are good but since you might not want to just buy all of them right off the bat (there is a bundle available), how about I rate them from personal favorite to least favorite?

1) Kimamani Summer Vacation - Good high energy song with great visuals. A vacation to remember.

2) kissxkissxkiss - A bit down-beat compared to their other stuff but still a great song and very surreal visuals.

3) Nozokanaide Naked Heart - One of their newer songs and very polished. Has interactive elements.

4) Astral Piece - Great song and visuals but this one's a solo featuring only Niina (Shikiri #1!, lol).

5) Kisekiteki Shining! - Their first song and it's visuals are a lot weaker compared to their later songs. It's just a plain stage with a lot of effects going on.

There is also a live concert recording available that includes all of the above songs which is a great starter pack but it does lack all of the unique visuals of the music videos. It does have a lot of unique things of its own, though, like a 3-person version of Astral Piece and romaji karaoke.

Overall, I would recommend everything they make but if you don't want to take the full plunge, at least give a song or two of theirs a try!

It's short, but good. I would recommend getting it on a sale.

A little ashamed I bought this. Mostly because it is only one song and an incredibly short experience for $3.50!
It is well made, but there have been stuff like this since Oculus Dev2. Save your cash until it drops to $1.

These Hop Step Sing! "games" are well made but very expensive for the amount of time you're likely to spend in them. The only one that's worth considering even at a discount is the Summer Vacation one, and this is coming from a filthy degenerate.

Fantastic show with crisp graphics and presentation and incredible motion. The physics on the outfits etc seem really well done and I didn't spot any clipping which you often get with things like this. If you like this kind of anime idol music you'll more than likely enjoy this experience.
One caveat, on oculus after loading the first viewing drops somes frames here and there, randomly this doesn't happen for any subsequent viewings, only the first after loading.

Cute single with nice visuals and great vocals!

Cute, hot, colorful, fun music videos. Great outfits.

Out of all the Hop Step Sing! VR experiences, this was probably the weakest. You could skip this one if you want.

Really emersing and great singing. Just wich there was more than just one song. but really worth the money ^_^

Good music video in VR 360. Works as intended. I had no noticeable problems. The graphics are cartoony. The quality varies for some reason between the videos but they were clear and viewable for me. The dev did a good job of creating various scene changes in each music video performance which made the whole experience more enjoyable. The girls stay away from reach most of the time but do come close in some parts and on the train they sit right next to you and have you hold their purse and stuff which was cool. This is a visually pleasing and colorful VR creative experience. You also have something in hand to stream colors in the air while the concert goes on if you choose. It shows what could be if someone takes off with this idea and brings in our favorite real life performers to do the same. But at the very least our anime characters can really come to life.
