Morpheus, I haven't really had any selection problems. Sometimes I have to try my search with and without spaces between the words.
I don't really like limewire, it seems like the waits are much longer, on morpheus you just pick a song and then right click and do find more sources for download and it'll usually kick off the wait and find the fastest possible person. On movies it usually ends up downloading from about 6 or 7 different people, since it's constantly finding whoever is fastest.
