I dj in my spare time, 2 songs I cannot play are Perfect Day - Lou Reed and I'll be missing you by Puff Daddy.
A friend told me they have tried to overdose on pills and the song Perfect Day was playing on the radio - this was a few years back but still clear in my mind. We had driven to Brighton to walk along sea front when she started to talk to me about her marriage and the problems (well one it was the *******(feel free to use own words) she had married. And she couldn't see a way out....just made me feel a ****e friend as she had never explained before.
Puff Daddy - not only the song that was played when Ray Jones parents came onto the pitch after his sad death, but also at a friends mothers funeral.
Also love Hurt by Johnny Cash (previosuly listed above). Nine Inch Nails version is good - but the late Mr Cash sings it with a lot more feeling as it is stripped back.
