Alpha Betta covered Aitakute Ima yesterday. It was nice. Also quite convenient for comparison, if only out of idle curiosity, since most vsingers have tried singing it. The Japanese equivalent of Whitney Houston, so to speak.
https://files.catbox.moe/gnifon.mp4There is room for improvement, certainly. For instance, around 2:55, "waratte iru kana" was a missed opportunity for belting. And the song calls for vocal switches often. As can be heard in Noa's version around the same timestamp.
https://litter.catbox.moe/89hq8q.mp4In Alpha's defense, it's just one song, and she already did a better job than quite a few others. Also, I haven't heard any vsinger pull off the most important switch "ima aitai" at around 4:20, half as well as in the live version of the original song.
