Last week I was using grooveshark at home, when suddenly it opened a new tab showing that malicious "Windows Update" virus advertisement. This has been a problem with grooveshark in the past, and it's very ridiculous that they haven't sorted it out yet.
There are a whole heap of issues it is ridiculous that they have not worked out. Mislabeled songs, incomplete songs, poorly organized library, low quality tracks, viruses, partial albums.... etc...
And from what I understand also they haven't sorted out the whole licensing issue behind the music they serve.
