Ist spiralfrog.com sicher?

Ok, i've been using this for a while. Lots of people seem to have questions on this site, so I will try to be as neutral and informative as i can. The problem is that most people do not know what this site does, so this post is basically an explanation. Spiralfrog lets you download music for free and they pay the artists and record labels as well for their copyright. How? It gets money each time you click on an ad in the website. The good: 1. It has about 3 million tracks to download. Based on my experience, if you're looking for a popular song nowadays, you have about a 45% chance of finding it. Has: Rihanna, Katy Perry, Coldplay, Akon, Ne-Yo, Kevin Rudolf, Kanye West, 3 Doors Down, older songs of Boston, Daft Punk, Eminem, Fall-Out Boy, Nine Inch Nails, Nirvana, Hinder, Bob marley, Queen, The Who Does Not Have: T.I., Beyonce, Britney Spears, Jason Mraz, Pink, ACDC, Metallica, My Chem. Romance, Eagles, Led Zepplin, Green Day's American Idiot (has older songs), Basshunter, Linkin Park, Pink Floyd, Obviously i can't cover everything, but these are a few off the top of my head. Tried to cover a few different genres 2. It's free. Really. No rebates or any silly stuff. See "the bad" for the catch 3. No spyware or viruses. You do have to download a (small) download manager, but that doesnt screw your computer or anything. It does run 24/7, but I have yet to see any slowdown on my computer 4. These are good quality files too, and all of them are at 128 or 192 kbits/sec. Same quality as if you were downloading from wal-mart or any other store. All are direct downloads, no torrents or p2p stuff The bad: 1. You have to log in once a month to keep your songs playable and so you can see their ads (once every 2 months if you don't plan on downloading new songs). Sounds like it could be obnoxious, but there actually aren't that many ads. Check the home page if you don't believe it. No pop-ups. And no, this doesn't mean there are ads IN the music files or anything like that... 2. The real turn-off for people. The files are .wma format, which means that they must be played with windows media player or compatible devices (see site for a list). No ipod, itunes, or zune. .wma files are allowed have digital protection embedded in them, but ipods and zunes can't play them. Same reason ruckus, rhapsodytogo, and napstertogo have restrictions like this. 3. The files are protected and have restrictions (only the ones you download from spiralfrog of course). The first is that they expire after 60 days from last login to spiralfrog.com. The second is that it can be sync-ed to up to two portable devices that can play .wma files (see site for list - no ipods). No burning to a CD. 4. Yeah this sounds great and all, but you may ask, "do they really get that much money from ads?" The answer is no, and they're losing money. It's been on the web since 2007?, but it is possible that they go under someday, there's no way of knowing. This COULD mean not being able to renew your music liscences for the songs you downloaded from the site, but this is purely speculation and don't take my word for it. There seems to be a lack of third-party info on this company in the internet, so this is why i posted this long and detailed post, for those of you interested. And hopefully to enlighten people because I like this site and would not want to see it go under. My recommendation for this service? Try it out. If you like it, cool. If not, go back to itunes or whatever, there are no catches. By the way, there are a couple other sites based off of the same idea, but I would not recommend trying them (cough ez-tracks.com, Qtrax, etc. cough).
