Fun thing that's extra noticeable with these songs, the performances in the episodes are "live" in the sense that they did recordnon-OST versions with the bottleneck and Bocchi's guitar cutting out when the string breaks. Conversely the OST has the full length version but its without the slide since its the song "as it was supposed to be played" essentially. Basically the music has such attention to detail AND it helps build a really fun album (which I may or may not have bought).
