Sup guys! I just got a new cell phone and I want to customize it with video-game (and why not anime) musics and sounds. Basically for incoming calls and sms.

What do you suggest? Also, any good websites with a good library for that purpose?

Depending on your phone, this could be really easy or a bit of a pain. What is your phone model?

Nokia E51
Basically it reads mp3, acc and (not sure if) .wav

You can try looking around. You can try requesting things here, but not a whole lot of people collect sound effects here it seems. entertonement.com seems to have a good few, but most of the time it depends entirely on what you're looking for.

I see...
I'm looking for random stuff. Anything related to videogames would be nice. From Team Fortress 2 to 8-bit retro style soundclips.
Actually it would be nice to have a big .rar with tons of sounds so I can listen and choose :)
I'll google around also...

Maybe other people have had an easier time of it, but I find sound effects to be the hardest to find, and I'm usually looking for them for the same reason you are :D

Now, if you're looking for music as opposed to sound effects, you can probably find anything you need right here in the forum if you search.
