I'm new to Mac and trying to find the software that best suits my needs. I love foobar2k for win and Play seems very similar in focus (sound quality, formats and simplicity). I figured I could ask some tips from people here who seem to have similar preferences. First, am I right in my assumption that all Play does is keep an internal database with metainformation about my files and doesn't move/change/delete files themselves (excluding Tag-integration which obviously edits files).?
1. Tagging. Is it possible to add custom tags to files (like "party", "blaeish", "chill" etc) and use Play to search for those (using smart search?)? What software is best to use to manage such tags? "Tag"? This may sound noobish, but I have only found how to edit genre, artist, etc. I want my own tags =)
2. Managing library. I have a large library and very specific preferences on how it should be ordered. I want software to ASSIST me, which I can trust will not do any magic-stuff. Basicly I have my files in a location ordered the way I like and nothing should mess with that (thats why I like Play - it has a meta-library, without actually affecting the real files), but hopefully I could have some gui/integrated with play maybe to help me move/rename/retag/delete/add music.
3. Visualizations. Is there anything that integrates with Play or some standalone software with good visuaization?
4. Crossfade. How can I have crossfading tracks with Play?
5. Gui. Saw some thread about adding albumart to Play. Such visual elements would be great. It would be nice to be able to configure the interface in Play a la foobar, but better. I imagine something like a theme, which can be easily distributed as one file. This may be falling out of Plays focus, though. On the other hand, simplicity doesn't exclude polish =)
I apologize if this post is sort of OOT, but I'd really like to find answers to these questions because they would make my life so much better =)
Thanks to everybody for reading this and writing useful replies

Cheers!
