hmm, the network is quite dynamic. Searches go through each of your ultrapeers, then through each of their multiple ultrapeers, etc. until the search runs out of steam. But some of those leafs & ultrapeers change from one minute to the next at times so different results can occur.
Are you using LW 4.8.1 or 4.18 ? Just checking if it was a typo.

The reason I'm asking is because versions of LW after 4.17 will no longer give upload slots to versions older than LW 4.14. So if using 4.8.1 which was my favorite version until many versions later, you may be missing out on connecting to 'many' of the newer users. (I'm using both LW 4.16 & 5 so getting best of both worlds with 4.16.)
My advice would be to search something else for a while. Then go back to searching what you were originally after 30 to 60 or 120 mins later. That's what I often do.
You may be connecting to some poorly responding ultrapeers, not returning or passing on the search messages.
LW 5 is missing many tools from LW 4. It's not really a good version for experienced users.
BTW please do not mention artist names or titles of copyright songs. We need to keep such things off the forums for legal reasons.
