>>3788204>but i have a feeling it's probably not the kind of stuff I'm into.There are vocaloid songs of literally every single genre out there, though admittedly most of the more famous ones are j-pop/rock/electro stuff. I'm sure you can find something you'll like if you look for it though. I'll just leave a few of my favorite popular songs from some producers who use Len a lot, then:
https://www.youtube.com/watch?v=u5mHVUwDf_0 - Neru is one of the most popular J-Rock vocaloid-P ever, he did some angsty nihilistic stuff in the past but his recent songs are more upbeat (still nihilistic though)
https://www.youtube.com/watch?v=QuLwvlw6_uU - he's often paired with Rin in songs, this one is by Giga-P, very famous and talented electro-pop producer. He's also notorious for having some very catchy pervy Len songs
https://www.youtube.com/watch?v=qHjIfbO-bP8 - by Nem which is still one of my personal favorite producers, he does a mix of jazz/rock usually and tunes Len a bit deeper than most people, sounds very nice IMO
https://www.youtube.com/watch?v=cwLlHFMlBNQ - by Three which is a producer that got very popular in the past couple years, he's gone some very varied and unique songs
This is all really just scratching the surface though, if you really want to get deep into the rabbit hole, start by checking the songs they play on live shows or in the games, find some producers you like, look for more songs from them and go from there
