I always see comments on youtube videos and things with people saying songs have helped them through tough times and given them real inspiration.
Personally I've never really had it with an Avril song, but I have with a Snow Patrol song, 'This isn't everything you are' when I was going through a bit of a tough stretch earlier this year.
I'm sure you have your stories.
Apologies if this has been done before. I'm bad at actually finding things with the search feature on bandaids
