Best table structure

Please can someone let me know their opinion on the following: I have written some code for submitting a top 20 music chart online. I use the following to insert into mysql: INSERT INTO chart (name, chartpos, artist, title, label) VALUES ('$name', '1', '$artist', '$title', '$label'), ('$name', '2', '$artist2', '$title2', '$label2'), ('$name', '3', '$artist3', '$title3', '$label3'), -------------- repeat til ----------------- ('$name', '20', '$artist20', '$title20', '$label20'), Another page queries the table and sorts by name (multiple people submit charts) and latest date. My question is this: Would I be better keeping this format and inserting multiple rows on each submit, or to have one row for all 81 variables ($name, 20 x Position, 20 x Artists, 20 x Titles, 20 x Labels.) I know that the latter will be easier to query. Also, without maintenance, the size of the table for the current method will get extremely large. Will that affect server performance? I am still a newbie, so plain explanations would be most appreciated. Thanks very much in advance. Tom
