It is actually legal to download almost anything on the net, although it is illegal to distribute or sell the things you download for profit. That's the borderline and a lot of people get confused by saying that it is illegal to download anything in general.
Mediaworld provides an illegal MP3 download service. They provide users with a database of songs to download straight to their computer. As users do not pay to download this music it is an illegal service.

You can legally download these for a small fee from Amazon.com's Unboxed service. They are licensed to sell episodes of Avatar the Last Airbender.
Limewire and file-sharing services are legal. You can download music for free from the service but you should not download copyright protected music, as that is illegal.
To download Adobe Flash Player legally, go to the official site of Adobe Updates, downloads and service information can all be found here. Simply click on the "download" link and let the application run until it has notified you that the player has successfully been installed on your computer.

You can, but it requires either a pay to use service or a lot of technical know-how, but it is also illegal.
You should go to their website an see what packages TalkTalk offers for broadband download speeds. If it was me, I'd also look on the web for reviews of the service to see if others are actually getting the download speeds they purchased.
You can use sites such as Youtubedownloader or Youtube-MP3. Both allow you to download songs from Youtube videos. If you want to download them legally, I would suggest Trialpay or some other service similar.
