Audiosurf 2 is barebones in terms of its presentation and features. Whether or not you'll enjoy it will depend on how much you like music. If you absolutely love your music and just want a fancy excuse to listen to it, Audiosurf 2 is (still) one of the best options on the market. If you're looking for something with more complexity, a game like Crypt of the Necrodancer or the recently released Soundfall are fun alternatives.
There was also the whole controversy about the developer stripping support for YouTube's API over undisclosed matters. Given what happened with many Discord music bots that used YouTube's API, it seems almost prescient, and I wouldn't be surprised if something eerily similar happened. You can still technically mod it back into the game, but here's where I have to be upfront with you:
it's a nice feature, but it was kind of janky even when it was officially supported. You have to keep the video in the corner of your screen, which can get very distracting if what you're watching is a music video and feels pointless if it's not. The kinds of videos you're allowed to use are never specified, so the best thing about playing a rhythm game set to a YouTube video (I.E., giggling as you slowly move to the beat of an ASMR video or an old meme) never delivers itself with consistency. In terms of playing to music, it mostly works at finding what you're looking for, but it's only ever guaranteed if you're looking for something with many views. Other than that, it works, I guess. If you ask me, I think it would be neat to have a sequel to this that does the exact same thing that Beat Hazard 2 did (instead of capturing audio from a specific source, it just records whatever is on your desktop and charts it). It might be a little janky, but it's a fantastic compromise that deserves to be in a much more interesting game.
