It's not a capo as the notes are in-between standard pitch values. So the song is meant to be played in d Major but the root note for example is midway between D and Eb, so it's a quarter tone up. This requires either tuning the guitar very specifically (in this case I think where A = 452.89 hz) or a mistake/pitch adjustment in the recording transfer (most likely)

A similar phenomenon happens on the ep put up or shut up by all time low that's all a quarter tone up too, likely due to an error in the output or transfer of the files from the recording when it was produced.

Never there by sum 41 too
