A way to slow down MP3s without altering the pitch?

If you have a mac there is a FREE app (or at least free when I got it) in the app store called "gAssistant". It can slow down/speed up music without altering pitch, but if you want, you can alter the pitch for transposing or what have you.
 
Hardware Wise I use the Boss Micro-BR 4 track recorder. It's pocket sized, you can put any of your MP 3's on it to practice with (plug in your bass and headphones), it has a built in tuner and effects, and will slow them songs down without changing pitch. Best piece of practice equipment I own.
 
The amazing slow downer isn't actually free.

Best practice is virtually identical and works just as well. Apparently there is less noticeable loss of quality with ASD, but I think you have to be pretty picky to worry about it, after all it's a tool.

Not free but worth every penny and it plays MP4's also with no digital breakup at any speed.

Best Practice is my chosen tool for slowing songs down and pitch shifting. I use GuitarPro a lot to loop sections I need to learn though. The ability to increase the tempo gradually on each loop becomes invaluable for learning covers quickly. Downside of GPro is the sound quality isn't that good and you are at the mercy of the available transcriptions on the net. Most are accurate enough though.
 
Quicktime. Under File -> Open put the location of the MP3. If it's an iTunes, click on Get Info and copy the location to put into the Open of Quicktime. Then in Quicktime Ctrl K to access the speed controls. I use this because I learn and play 90% with iTunes on my computer. Works great.
 
I have used the Tascam MP3 Bass Trainer, MP-BT1 for a couple of years now I guess. I think there is a newer version but mine does fine. I can not plug it into my Carvin BX500 I like to use over my home practice rig, so I keep my little Acoustic 260 over my BX just to use the Bass Trainer. It is very handy and one of the best training aids I ever used.
