Details : Ex-Girlfriend became a hit in Modern Rock Top 20 by reaching number #2 on the Billboards but never became a hit in the Billboard Hot 100 (even no entery). In other countries in the world it became a hit. In Australia it even reached number #7.

The orginal version of Ex-Girlfriend is slow song by the way.
