I installed Build 2.42.40 of Version 8.0 on my Model S (refresh 60) Friday night. Its release notes say: New 8.0 Enhancements There are multiple improvements to the USB listening experience. You can now use search to quickly find a song, artist, or album on your USB. Or use the alphabetical index to select music from long lists. Songs in the artist view are now grouped by album--particularly convenient with artists with multiple albums. Performance has also been improved, including faster scrolling of lists and faster USB loading when you return to your vehicle. Since this is my first 8.0 release, I can't compare it to earlier 8.0 builds, and can't say what's faster. Scrolling seems reasonably quick, and the column of letters that lets you jump to songs alphabetically is there, as it was in Version 7.1. Overall, I was satisfied with how my own USB music appeared within Artist, Album and Song collections (following how they appear in iTunes from which they were copied). I verified that the search feature returns results both from Streaming and USB. I inserted a USB drive with 1800 songs on it, and it started loading at a rate that seemed a bit faster than 2% per second. When I returned to the car, I didn't specifically notice any delay in the accessibility of USB music. I spent some time with Streaming too and I did not observe the cut off at the end of the song that has been widely reported. I may not have listened long enough to be sure this issue is fixed.
