I feel that the WipeOut series are very underrated, there are some great racing games but I find these lots of fun, besides being incredibly challenging on faster speeds and having an outstanding soundtrack.
It's a futuristic racing game where you take control of an anti gravity ship of choice and win races of various types. You have weapons you can pick up and use to eliminate other opponents. There are various types of races, with different objectives. For example, eliminator, where you must get certain amount of points by attacking other players, or Zone mode, where the speed increases constantly and you must survive as much as possible until you destroy your ship by hitting the walls too much.
Two gameplay videos (old and new)
Zone Mode (unfortunatly it's in cockpit view, but it was the best gameplay I found)
Some music from the game

I know it's a lot, but most people know the series for it's music.
If you have the chance, grab one of those for the PSP or even on the Playstation Store.
You can also play the older ones on an emulator.
