Valorarme comes from the verb valorar, meaning 'to value' or 'to appreciate'. The -me ending makes it reflexive, so it means 'to value myself' or, in this context, 'to value me' (referring to the speaker).

Trebol Clan and Julio H bring us a track that's all about missed chances and moving on. The song's speaker is pretty clear: someone had their shot at happiness, but they didn't take it. Now, that person is back, full of regret, but it's too late. The speaker's feelings have changed, and they've found someone new.
It's a classic story of not knowing what you have until it's gone! The lyrics hit hard with lines like "Pudiste hacerme feliz pero no quisiste" [You could have made me happy but you didn't want to] and "El amor que sentía por ti ya no existe" [The love I felt for you no longer exists]. The speaker was tired of waiting for the other person to make up their mind, and now they're done. No more chances, no more waiting around – it's "demasiado tarde ya" [too late now].
