Depends on the hard times.
Like for mental health problems, probably Motion City Soundtrack's Commit This To Memory, Even If It Kills Me, or I Am the Movie albums.
For feeling trapped in a small town, The Weakerthans' Reconstruction Site or Left and Leaving albums, or anything by Green Day up until American Idiot. The Weakerthans' song Plea from a Cat Named Virtue (and the followup songs) also often snap me out of my depression bc it gets me to think about my own pets depending on me. Be forewarned, the trio of songs about Virtue the cat are actually really sad and more like a cautionary tale of sorts 😳
When I felt like a screw up making bad decisions, the song Thrash Unreal by Against Me! or Amy Winehouse's Frank and Back to Black albums.
Also Lizzo's song Good as Hell really helped me through a period of time where I felt like I had absolutely no one in my life. That song worked a bit differently for me... all the other songs and albums I mentioned helped bc it just made me feel normal to hear other people putting to words what I was already feeling, whereas her song helped bc it was the opposite of what I felt and seemed more like someone giving me advice on how to change things around. Extremely uplifting.
