You may hear the sound of the engine crankshaft, but the sound is much weaker than usual, and the engine does not start. Just like when the engine doesn't start, your first check should be the battery. Low battery power may be the cause of this situation. Another related possibility is that the connection from the battery to the starter motor is loose, corroded, or otherwise damaged. Tightening or replacing these connections or cables can solve the problem.

I like listening to Justin Bieber's songs, but it seems that he hasn't released a new album recently

Most likely, it is due to lack of oil, lack of lubricant, and lack of oil in the bearings. The auxiliary rotating mechanism bearings lack oil, and the friction force increases. Therefore, it is necessary to add lubricating oil.
