A Taylor Swift fan has some Bad Blood with her best friend after having a severe disagreement over her choice of wedding song.

In a post to Reddit, the woman explained one of her close friends is having a Taylor Swift themed wedding which she was ‘beyond ecstatic’ about – until they had a huge fight about one seemingly small thing.

‘During the ceremony she wants to play the song Lover which is one of her favorite songs,’ the friend explained in a post on to r/TrueSwifties subreddit.

‘I get that but I’m trying to tell her that it would be insensitive to play Lover since Taylor specifically added it to her denial playlist and it would be invalidating that,’ they explained.

While the bride argued it is her wedding and so she can play what she wants, the pair still argued over it.

‘We had a fight about this yesterday and we haven’t spoken much since but I love her and I don’t want to miss her wedding,’ the friend wrote. ‘Please share your thoughts ASAP.’

The ‘denial playlist’ the user was referring to is a select list of playlists released in April, put together by the popstar to stream on Apple Music.

The five playlists represent five different emotional components of a breakup.

Each contains some of Taylor’s own past songs, including old hits like Bad Blood and We Are Never Getting Back Together.

The playlists are indeed based on Elisabeth Kübler-Ross’ famous five stages of grief – denial, anger, bargaining, depression and acceptance.

The first Apple Music playlist was called I Love You, It’s Ruining My Life and is full of old Taylor Swift songs connected to the denial stage. 

The majority of the comments on the post slammed the so-called-friend for her bizarre attitude – assuring her Taylor Swift herself won’t care if the bride plays the song.

‘I’m sorry, is this a serious post? First of all, it’s your friends wedding, not yours, so you don’t get to tell her what songs to use or not use,’ one Reddit user commented.

‘Second of all, you need to take a breath and back out of this weird parasocial thing with Taylor you have going on. Insensitive? To Taylor Swift? Are you serious? I’m so baffled I have a hard time believing this is a real post an adult human who has friends old enough to be getting married would make,’ they added.

Another agreed, writing: ‘Girl… I’m positive Taylor would be okay with it. besides I’m pretty sure she won’t be at the wedding.’

‘FFS, really? How can you not see this is insane behavior on your part?’ raged a Reddit user, also pointing out it’s not her wedding.

‘If you genuinely feel so strongly about this then I suggest you don’t attend the wedding, burn all bridges with this friend (and probably any mutual friends you have because I can’t see any rational person backing you up on this) and then check yourself in for some intensive therapy,’ they recommended.

‘I can tell you right now, standing up for Taylor Swift, a celebrity who will never care about you on a personal level does not give a single care what songs of hers people play at weddings,’ another wrote.

The user urged the friend to embrace her friend’s wedding and remember that she’s just a fan of Taylor Swifts. 

‘She will never notice you rallying for her,’ they pointed out. ‘Your friend is someone that is actually, physically in your life, she is someone who you have cared for and vice versa, your friends feelings should always come first over whatever parasocial fantasy you are living in.’
