Former NBA star Joe Smith is paying lyrical tribute to his fallen friend Lamar Odom ... recording an emotional song for his former Lakers teammate called "If I Die Tonight."
Odom continues to fight for his life after being found unconscious in a Las Vegas brothel Tuesday ... and, although he's shown some signs of improvement recently, a long road remains.
Smith played with Odom on the Lakers in 2010-11 and tells TMZ Sports he recorded the track hoping it would lift the spirits of everyone who cares and loves Lamar.
"I want [the song] to give the people some faith and motivation... empower them. Give them hope that Lamar's going to be okay."
Although the song seems to be asking the question of what the world would do if Odom were to pass away, Smith says reaction has been positive ... even moving some to tears.
"The response has been great. People are enjoying the music. Some people even said it brought tears to their eyes. That shows people are hearing the song and feeling the emotion in it."
