The song at sisters funeral..

This may be a little weird to ask but my sister died when I was 12 that's been 13 years ago (awhile, I know) one of the songs that played at her funeral was Eric Clapton no tears in heaven..I hardly ever hear it on the radio and it used to be on my phone but deleted it bc every time it came on I turned it bc I always felt guilty, like I shouldn't be listening to it. I heard it today on the radio and I listened to it and of course I cried bc of the memories it brought up. But I really like the song. Would it be weird if I listened to it? Should I not like a song from my sisters funeral?
