Best way to store songs in sql db

What is the best way to store songs or tracks in a music SQL database? Currently, I am using the following database structure: table: musictable ID album band genre album_cover song1 varchar (50) song2 varchar (50) song3 varchar (50) song4 varchar (50) song5 etc... There must be a better way than this? I was thinking of breaking the table up into two tables. One table contains just songs and album and the other table contains genre, album, and band. Another problem I encountered is printing out the tracks. If song4 and higher are empty, then I don't need to print them. How do I prevent printing empty fields? I probably just need a loop and if statement. I use MySQL with Linux and PHP 3.0.16
