How to add music to playlist?

I'm using My Music on my Droid4 and I've been having a problem with the playlists.

I recently started trying Ubuntu One music streaming and now it feels good. However I have a problem here: I used to have several long playlists for myself in Rhythmbox (300-500 songs each playlist, in my favored order), and I really liked to play songs from the playlist instead of shuffling all songs.

Does m3u2u1ms work only on music purchased though Ubuntu One?

I have a Samsung Galaxy S2 and I usually download my music from my computer to my phone via Kies. The last time I did this was probably two weeks ago without any issues.

Now, I've managed to upload a set of songs to my phone but for some reason, they're not showing up on my Music playlist.

so ever since i've downloaded android 4.1.

I recently got CM9 on my Xperia Arc lt15. Overall I'm happy with it except Apollo. I find it a pain in the @$$ to make a playlist. You have to press every freaking song to add it to a playlist. Why not have an option to select some or all songs? Or am I doing it wrong?

I'm having a bit of an annoying problem with Banshee. I have a library that's not so big, only 300-400 songs. However, I'm the problem arises when I play songs. When I double click to play a song, it plays normally, as expected. But during a playlist or my whole library, or even a playlist with a single song being played, something funny happens: It starts the next track f.ex.

Hi I have been using Xperia RAY for quite some time now..

When it was on Gingerbread..

Hi all! I have Fedora 11 and amarok-2.1.1-1.fc11.i586. Last week after some updates and for now I have a problem with amarok, it doesn't want or can't to make a list of song for playing!!! So it can't play anymore.

All the buttons and menu items like clear playlist, new playlist, add songs to playlist etc. don't do anything!!!
