Bluetooth transfers

I've been transferring songs from my Mac onto my cell phone through Bluetooth to use them as ringtones, but how do I just transfer parts of songs instead of the entire thing?

The only way to get part of the song onto your cellphone is to cut them before you transfer it. I am not too sure about software in mac, but if you have got windows installed on your macbook. "Mp3direct cut" would be a great software to do the job. It can be downloaded for free and easy to use too;D Well then you just have to save the file and transfer it to your phone. Hope this helps
