The song "No Reason" by Grinspoon appears to be about a relationship that has come to an end. The lyrics suggest that the person the singer is addressing has run out of explanations and excuses, as indicated by phrases like "u've run outta all ur answers" and "u've run outta ammuntion." The line "But u could go, down so low, No-one'll eva hear u call" suggests that the person they are talking to is alone and facing consequences for their actions. The phrase "I've got no reason" repeated throughout the song indicates that the singer no longer has a reason to continue fighting for the relationship. The chorus expresses the idea that the person they are singing to could have had their love and support, but now they are giving it back because it is not enough. They want this person to understand that they were the right one for them, but now the singer sees no reason to continue the relationship. Overall, "No Reason" portrays a situation where a relationship has reached its breaking point and the singer has lost all reasons to continue.
