Convert 160 videos to audio files and then upload to a website...

To start with there are 160 youtube videos that I want converted to an audio format mp3 or another audio format. Each file must be titled as they are on youtube which you could just copy and paste the titles. Then upload the audio files to a free website where people can listen to the songs online or download the songs for free. I am not sure of what website to use so you will need to find out which free website is best to use. Thanks
