I've downgraded to mysql 5.6 and everything is behaving itself again, so I'm happy for the time being. 

In your tests, what size does the MyMusic db have? I would suggest filling it with an awful lot of data in order to simulate this behaviour. For example:

Code:


mysql> select count(*) from song;
+----------+
| count(*) |
+----------+
|   103294 |
+----------+
1 row in set (0.02 sec)
