I don't like to call it depressing music, but more like Reflexive music, because it puts you in that mood that you look at your life and its goings dunno just my opinion, but heres my list:Naked - Goo goo dolls3 Am - Matchbox 20Time after time - Matchbox 20This years love - David GrayThe blower's daughter - Damien RiceOver and out - foo fightersTimes like these - Foo fightersEverlong(acoustic) - Foo fightersNovember rain - Guns n RosesIris - Goo goo dollsbetter days - Goo goo dollsBlack balloon - Goo goo dollsMr. Jones - Counting crowsRound here - Counting crowsHere comes horses - Tabitha's secretDreams - Fleet Wood MacAnything by Charlie Loop (its a not very well known band)I've got more but i don't remember now, but if you like relaxing instrumental music i would recommend aything by Sigur R?s, a very good song by them is Hoppipolla.
